Published: March 2022

Abstract
Two similar but independent experiments were conducted to control yellow aphids on pecans at Monroe and Shreveport, LA. At Monroe, the experimental design was a randomized block design consisting of 2 blocks with 3 trees per treatment per block. The trees were "Stuart" and "Schley" cultivars. Applications were made on June 28 with a Meyers 2A42 sprayer with each tree receiving ca 33 gal of spray. Evaluation occurred on July 2 by counting the aphids present on 10 randomly selected compound leaves per tree. At Shreveport, the experimental design was a randomized block design consisting of 3 blocks with 2 "Success" trees per treatment per block. Applications were made July 9 with a John Bean 957 sprayer with each tree receiving ca 33 gal of spray. Evaluation occurred on July 13 by counting the aphids present on 10 randomly selected compound leaves per tree. Data were subjected to analysis of variance.

Published: March 2022

Abstract
Slender white beans were planted using a Planet Jr in 50-ft rows on 38-inch centers on August 14,1974, near Clinton, North Carolina. Eight single-row treatments arranged in a randomized block design with 3 replicates were compared to an isolated check. Soil type was Norfolk sandy loam with adequate irrigation. Insecticides were applied on 3 dates (September 3, 12, and 19) with a CO2 back pack sprayer at the rate of 100 gallons of spray per acre and 40 psi Copper Count N was applied to the check plots and included with the insecticide treatments for routine disease control. Mexican bean beetle adults were counted on 3 occasions from the entire row. A damage index was obtained on October 3 by scoring foliage damage per replication. Yields were taken by hand on October 3, 1974, (10 row feet per replicate) and weighed.

Abstract
Experiments A, B, C, D, E, and F were 7 × 6, 4 × 6, 6 × 6, 5 × 6, 7 × 6 , and 6 × 6 randomized complete block designs respectively and were conducted at Presque Isle, Maine on land that was sown to oats in 1975. The planting date was June 4, 1976 for all experiments. In each experiment the 9.1 m space between blocks and the 1.4 m space between columns and at the sides and ends of the experiments were sown to oats at planting. Each plot consisted of 4 rows of potatoes 0.9 m apart and 15.2 m long. The 57 g healthy seed pieces were hand planted 30.5 cm apart. Fertilization and hilling practices were normal for the area. Late blight control was effected by weekly foliar applications of Rohm & Haas M 45 (2242 g ai/ha July 10 through August 31, 1976). Soil applications of insecticides were made by hand with a plastic tube applying previously weighed amounts of insecticide into the furrow just prior to planting. Foliar insecticide treatments were made with a Slosser sprayer (14.1 kg/cm2 and 1.2kl/ha) in combination with the fungicide. Numbers of aphids (by species) were counted on a top, middle, and bottom leaf of 25 plants in the 2 middle rows of each plot. When date of count and application are the same, aphid counts were made prior to application of the insecticide. Analyses of variance were calculated following transformation of the raw data using log10,(x + 1)- Means of the total number of wingless aphids were compared using Duncan's new multiple range test and then reconverted as given in the Table. The soil was classified as Caribou Loam, pH 5.2. Rainfall for June, July, and August was 112, 140, and 174 percent of normal. Temperature for the same 3 months departed + 3.5°, + 1.0°, and 0.0°C from normal.

Published: March 2022

Abstract
American Crystal hybrid 2B sugarbeets were planted May 25 in Bearden silt loam soil with good soil moisture at St. Thomas, ND, in two row plots 100 ft long with a 22 inch row spacing. Each treated plot was separated by two rows of untreated beets. Granular materials were applied in 5 to 7 inch bands ahead of the press wheel and lightly incorporated with drag chains. Post-emergence applications were applied June 12 in a 5 inch band over the row and lightly incorporated with drag chains. Injury to the beet plants from drag chains was minimal. Treatments were replicated four times in a randomized complete block design. The experiment was conducted under dryland conditions. Above normal rainfall was recorded during June and July. Sugarbeet root maggot populations were high with a range of 35 to 70 maggots per beet in untreated beets recorded on July 2 . Damage ratings were taken July 15 by evaluating 8 beets from each plot on a scale of 1-4 (I = no damage; 2 = slight damage, less than 3 small scars; 3 = moderate damage, less than 1/2 of the root surface damaged; 4 = heavy damage, more than 1/2 of the root surface damaged, the plant dead or dying). Treatments were evaluated from yield estimates based on two 36 foot samples per plot (721) from treated rows on October 6, 1975.
Sweet Potato Weevil Control, 1976
Authors: Waddill Van 
Published: March 2022

Abstract
Six inch stem cuttings of Nancy Hall variety sweet potatoes were dipped in insecticide solutions (Table 1) and allowed to dry. The cuttings were then placed in cylindrical screened cages (height = 17 cm, diameter = 8.5 cm) and maintained with the lower 1 in. in a small jar of water. These cages were kept in a greenhouse. Each treatment was replicated 5 times and arranged in a completely random design. Ten field collected sweet potato weevils were introduced into each cage at the following post-drying times: 1, 7, 14, 2 1 , 28, and 35 d. The numbers of dead weevils were recorded 4 days after introduction. Sweet potatoes (Purple Stem) for the field trial were planted 1 ft apart on Aug 26, 1975 in Rockdale soil. Plots were single rows on 8 ft centers, 25 ft long with 4 replications in randomized complete blocks. Treatments (Table 2) were applied every 3 weeks with a tractor mounted sprayer with 5 nozzles per row which delivered 100 gal wafer per acre with 250 psi pressure. A tofal of 9 applications were made. The plots were harvested Mar 26, 1976. Six pounds of potatoes (3 two lb samples) were collected from each plot and held in paper bags in the laboratory (approximately 75° F). The bags were inspected periodically and the number of weevils emerging over a 28 day period recorded.
Evaluation of Insecticides For Control of Insect Pests of Tomatoes, 1976
Authors: Waddill Van 
Published: March 2022

Abstract
Two tests were conducted at Homestead for control of several insects on tomatoes. The plots were direct seeded Sep 15, 1975 in Rockdale soil and later thinned, leaving a density of 1 plant per ft . Plots consisted of single rows on 6 ft centers 15 ft long. There were 4 replications per treatment in a randomized complete block design. Insecticides were applied weekly from Nov 13 to Jan 15 with a tractor mounted sprayer with 5 nozzles per row. Treatments were applied at a pressure of 250 psi in 100 gal of water per acre. On Dec 16 the number of leafminer mines and green peach aphids per terminal trifoliate of 10 randomly selected leaves per plot were counted. Tomatoes were harvested Jan 12 and 21 . The percent Southern armyworm damaged fruit was determined by examining 25 randomly selected fruit from each plot on each harvest date. Tomatoes for Test 2 were seeded Jan 12, 1976 in Rockdale soil. Plant density, plot size, statistical design, number of replications, application schedule, equipment used, psi, and gal per acre were the same as used in Test 1. On April 19 the number of living pinworm larvae and vegetable leafminer larvae per terminal trifoliate of 10 randomly selected leaves per plot were counted. The percent tomatoes damaged by pinworm feeding was determined April 16 by randomly selecting 10 mature green fruit per plot. Duncan's multiple range test was used to separate treatment means.

Published: March 2022

Abstract
Soil insecticides to control larvae of the corn rootworm were evaluated at five locations in Nebraska in 1976. Corn plots were planted May 6, May 4, May 11, May 12, and May 14 at Mead, Clay Center, North Platte, Scottsbluff, and Concord, Nebraska respectively. With the exception of the Concord test, all experiments were conducted on irrigated land. Each insecticide was applied in a seven inch band over the row (1.2 oz a.i./lOOO ft of row) at planting time and incorporated by a press wheel. Each treatment consisted of one row, 50 ft long. All experiments were arranged in randomized complete block designs with four replications/treatment. Treatments were evaluated for root damage in mid- July by digging five equally spaced plants from each row and rating the roots for rootworm feeding damage using a 1-6 damage scale (1 = minor damage; 6 = three or more root nodes destroyed). Yield was obtained by harvesting the middle 40 ft of each row and converting to bu of no. two corn/acre.

Abstract
A field (Tift loamy sand) was made into flat beds then divided into plots 4 rows (12 ft) wide and 50-ft long with 4 replications in RCB. The plots were divided into two 2-row sub plots treated and not treated with Mocap 10G at 8.0 lb ai/acre for nematode control. Each main plot was also paired with a 2-row untreated check plot. These and other insecticidal granules were broadcast over the beds by hand using a perforated can. Raised beds were then formed with a Vari-Tiller thus incorporating the granules. Sweet potato vine cuttings were transplanted the same day on Jul 25. Some plots also received granules broadcast by hand over the vines at root swelling on Sep 7. Plots were harvested on Dec 1 and 25 randomly selected roots per plant were examined for insect damage.

Published: March 2022

Abstract
The test site was located near Rising Sun, Cecil Co., Maryland. Damaged corn levels ranged from 90% to 100% at the test site and the field required replanting. Treatment plots for Test 1 measured 20 × 50 ft and were arranged in a randomized complete block design. Granular treatments were broadcast-preplant with Gandy drop spreader and the plots lightly disked before corn was replanted. In test 2, a 4 row planter was used with a different insecticide treatment in each box. 1) An untreated check, 2) Furadan was applied in furrow whereas 3) Counter and 4) Mocap in the remaining boxes were applied in a band over the row. These 4 treatments were stripped with the corn planter through a heavily infested section of the field. Treatments for both tests were applied May 31 and post treatment samples were taken June 25. Both stand and injured plant counts were taken from 75 ft of row within each plot for Test 1 and 25 ft of row in Test 2. Samples in Test 1 were taken from center 4 rows and in Test 2 collected at random within the treated field.

Fall Armyworm Control in Whorl-Stage Sorghum, 1979
Authors: Gardner Wayne A. , Schwehr Robert D. 
Published: March 2022

Abstract
Three tests were utilized to evaluate the effectiveness of various materials in controlling fall armyworms in sorghum whorls. The tests were planted in Cecil clay soil by conventional tillage methods on July 17’79. Test 3 was ratooned and fertilized on Sept 7’79. Hybrids planted were Funk’s HW 1762 (Test 1) and Funk’s G522DR (Tests 2 and 3). Treatment dates for the respective tests were Aug 17V9, Aug 29’79, and Sept 28’79. Treatments were applied with compressed-air sprayers calibrated to deliver 60 gal H2O/acre. Control was evaluated 3 and 7 day postapplication by counting larvae in the whorls within a 3-m section of the middle row of each plot. All plots were 6.1 m × 3 rows. All tests incorporated a completely random design with 3 (Tests 1 and 2) or 4 (Test 3) replicates. Some natural reductions in larval numbers occurred at 7 days post-application and were probably due to increasing plant maturity beyond the whorl stage.
Apple, Timed Leafroller Treatments, 1979
Authors: Hill Clarence H. , Cobb Leonard J. 
Published: March 2022

Abstract
Treatments were applied to full grown (approximately 15-yr-old) semidwarf Stayman trees with a Bean 35-gal/min hydraulic sprayer operating at 540 psi. The treatments consisted of 5 single-tree replicates in a randomized complete block design. A blank tree was used to separate all treated replicates. The trees were sprayed to run-off. Moth populations were monitored by the use of pheromone traps. Using trap catches as an indicator, the orchard was monitored for periods of peak egg hatch. Treatments were timed to coincide with first and second generation peak egg hatches. The first application was applied Jul 6 and intended to have maximum effect on the first generation of Variegated leafroller and tufted apple budmoth. The two subsequent applications were applied against the second generations on Aug 20 and Sep 4 . Other materials used in seasonal pest management were Imidan 50W (3 lb/acre) as principal insecticide on May 21, 31, Jun 12, Jul 23 and Aug 9, and captan as the main fungicide. Oil was applied on Apr 7, Phosphamidon on Apr 19 and Jun 12, and parathion on Jun 22. These materials were applied at the rate of 100 gallons per acre with a Hardie 525 airblast sprayer.
Sorghum Greenbug Control, 1979
Authors: Peters Leroy L. 
Published: March 2022

Abstract
Plots were arranged in a randomized complete block design in Clay County, Nebraska. Plots were four rows, spaced 30 in (76.2 cm), 30 ft {9.144 m) long, replicated 5 times. The 2 center rows were used to evaluate the insect population and for yield. Granular insecticides were made with a Noble metering device mounted on the planter. Banded applications were made with a 7 in (17.5 cm) bander. In-furrow planting time applications were made by directing the insecticide delivery tube into the planter shoe just behind the seed delivery tube. Liquid insecticides were made with a compressed air-plot sprayer mounted on a high-clearance vehicle. Relative effectiveness of treatments was evaluated by counting live greenbugs on 10 plants during the first part of the season, and counting greenbugs on 5 plants during the latter part of the season. Insect counts were subjected to analysis of variance using the transformation of v X + 0.5. The means with a significant F value of 5% or less were ranked using Duncan’s Multiple Range Test. Plots were harvested with a combine. Moisture determination was made of each plot sample, and yield converted to pounds of 14% moisture sorghum per acre.

Abstract
Soybeans were planted on May 25’78, at the E. V. Smith Research Center at Millstead, AL. This test was initiated on Aug 30’78, when 48 plots were deliniated and treated. Each plot measured 33 ft by 4 rows (40-in centers). Experi-mental design was a randomized complete block, 4 blocks each with 12 treatments. Treatments are given in Hie tables. Treatments were applied to post-bloom plants with a CO2 sprayer delivering 12 gal of mixed spray per acre. Post-treatment population counts were taken 24 hr after treatment as follows: a 3-ft drop cloth was placed between 2 rows, bean plants on both rows were shaken over the cloth (thus sampling 6-row-ft), soybean loopers and podworms falling en the cloth were identified Qnd their numbers recorded. This was done 3 times in each plot for a total sample of 18-row- ft/plot.
