Foliar Sprays for Control of Green Peach Aphids and Colorado Potato Beetles, Test 6, 1978
Authors: Powell Donnie , Mondor William 
Published: March 2022

Abstract
'Russet Burbank' potato seed pieces were planted on Mar 30 in Ritzville silt loam soil (Mesic Calciorthidic Haploxerolls) at Yakima, WA. On Jun 16, the insecticides were applied as foliar sprays in 40 gal/acre with a 2-row portable boom CO2 hand sprayer. The plots were 2 rows wide (5.6 ft) and 25 ft long. The potato plants were 12-14 inches high at the time of insecticide application. Each treatment was replicated 3 times in a randomized complete block design. Twenty compound potato leaves were collected from the lower two thirds of the potato plants in each plot at 3, 6 and 14 days after treatment (Jun 19, 22 and 30), and the number of green peach aphids (GPA) on the leaves was counted. The percentage of leaves infested with GPA was calculated. Few Colorado potato beetles (CPB) were on the plants at the time of insecticide application, but adults (CPB) began to invade the plots and on Jul 7 (21 days after treatment) the number of adults and larvae/3 m2 (3 m long × 1 m wide) of plant foliage per plot was counted. The data were transformed to Log X + 1 and an analysis of variance was performed by using DMRT.

Abstract
Plots were located at Lafayette, Indiana on the 0'Neall Memorial Farm property. Granular insecticides were placed in a 10-12-in band with a Gandy Ro-Bander and incorporated 2-3 in with a rototiller on May 20. Soil type was a silty-clay loam pH 6.3, O.M. 2.7%. Black plastic mulch was placed over insecticides and plants transplanted on May 24. Rows were 30 ft long on 10-ft centers, plants on 30-in centers in rows. Treatments were arranged in a completely randomized block design with 4 replicates. Temik and Furadan received no foliar insecticides, however all other treatments received Sevimol 4F (0.1 lb ai/acre) as a foliar spray on a 7-10-day schedule. On May 25, 450 striped cucumber eggs were placed in the soil alongside each plant stem. Total runner length was measured for 5 plants per treatment on Jul 2.

Published: March 2022

Abstract
The sweet corn utilized in this study was planted on April 26, 1982 on the Robert Wiggin Farm, Stratham, NH. Each plot consisted of a single 30-ft row of corn and each treatment was replicated 4 times in a randomized block design. The treatments were applied at the whorl stage when signs of leaf feeding injury were detected. Spray applications were made using a B 8 G CO, pressurized hand sprayer at 40psi and a volume of 26 gal/acre. The granular applications was directed into the whorls using a Gandy plot application. Evaluation for insect damage was conducted at harvest time on Jul 27 by examining all stalks and ears in each treatment and determining the percentage of injury resulting from European corn borer feeding.
Mushroom Sciarid Control with Fenvalerate (Pydrin), 1981
Authors: Rinker D. L. , Snetsinger Robert 
Published: March 2022

Abstract
Eight trays (0.61 m x 0.61 m x 0.15 m), each filled with 18 kg of Phase II horse manure compost were placed into each of 3 small mushroom growing rooms. Each tray was spawned with 110 g of MGA Cocoa Tan. Between 7 and 14 days after spawning (DAS), 1810 gravid female sciarids were released into each of 2,rooms; no flies were released into the third room. Pydrin 2.4EC was applied daily with fogger-mister at the rate of 115 g/1000 m starting 8 DAS in 1 of the fly infested rooms and continued to 76 DAS. A Pestolite Insect Trap (Model RD-1P) equipped with blacklight bulb, was used in each room to daily monitor fly populations. The growing methods used were typical for the mushroom industry. Mushrooms were harvested for 46 days beginning 38 DAS. Despite precautions, flies escaped from the infested rooms and became established in the “fly-free” control room late in the crop.

Abstract
The plot was planted May 4 in muck soil near Potter, NY on the Tony Sachel i Farm. Plots were single rows, 30 ft long, replicated 4 times in a randomized block design. Germination, damage, and yield data were recorded from the center 20 ft of each row. All seeds were sown and seed-furrow treatments applied with a hand-pushed cone seeder planting 9 seeds/ft and delivering 75 GPA through a gravity fed system. The foliar applications were made on May 19 and 24 using a CO2powered sprayer mounted on a cone seeder that delivered 75 GPA through a single TeeJet nozzle. Dithane M-45 (80WP) was applied in the furrow with each treatment except those already having a fungicide at 2.4 lb ai/acre for control of onion smut. Stand counts were taken Jun 1. Maggot damage was assessed by checking each row for wilted plants ca twice/week from the time of stand counts until harvest on Sep 21. Yield data were taken by pulling, topping, and weighing the onions in each 20-ft row.

Systemic Insecticide Treatments for Control of Green Peach Aphid and Colorado Potato Beetle, 1982.
Authors: Powell D.M. 
Published: March 2022

Abstract
On Jun 3 at Yakima, WA ‘Russet Burbank’ potato seed pieces were planted in open furrow in Ritzville silt loam soil (Mesic Calciorthidic Haploxerol1s) with a pH of 6.2 and 1.6% organic matter. The granular insecticides were dribbled through a hand-held, funnel-type applicator into the furrow over the potato seed pieces for the planting time furrow (PTF) treatments. Then the seed pieces were covered with soil. On Jun 23 when about 75% of these plants had emerged the post-emergence sidedress (PESD) treatments were applied. The granular insecticides were placed in 1-inch (2.5 cm) bands, 4 inches (10.0 cm) to each side of the seed pieces at approximately the depth of the seed with a tractor-mounted Gandy applicator. Each plot was 2 rows wide, (5.6 ft) and 25 ft long. Each treatment was replicated 4 times in a randomized complete block design. The crop was sprinkler-irrigated. The number of green peach aphids (GPA) on 20 compound potato leaves/plot was counted on Jul 6, 14, 21, 29 and on Aug 5 and 11. The number of Colorado potato beetle (CPB) on the plants of 6 row ft were counted on Jul 6, 29 and Aug 9. The percent of plant defoliation in each plot was estimated on Jul 6, 29 and Aug 9. The data means were tested with analysis of variance by using Duncan’s MRT at the 5% level.

Abstract
‘Russet Burbank’ potato seed pieces were planted on Apr 22 in Ritzville silt loam soil with a pH of 6.2 and organic matter of 1.6%, at Yakima, WA. On Apr 29 a furrow was opened over the potato seed piece and the insecticide granules were dribbled in the furrow with a hand-held, funnel-type applicator and the seed-pieces and granules were covered with soil. Each plot was 1 row wide (34 inch) and 19 ft long. Each treatment was replicated 4 times in a randomized complete block design. The potato crop was sprinkler irrigated. On Jun 15 (47 days after treatment) the number of Colorado potato beetle (CPB) adults and larvae and Lygus bugs on the plants in 15 ft of row per plot were counted and the percent of plant defoliation by CPB was recorded. On Jun 17 and Jun 26 (49 and 62 days after treatment) 20 compound leaves were collected from each plot and the number of green peach aphids (GPA), potato aphids (PA) and CPB eggs on the leaves were counted. The plants were so severely damaged by CPB by Jun 26 that the leaf samples were unsuitable for aphid counts.

Abstract
‘Russet Burbank’ potato seed pieces were planted on Mar 30 in Ritzville silt loam soil with a pH of 6.2 and 1.6% organic matter at Yakima, WA. Each plot was 2 rows wide (5.6 ft) and 25 ft long. On Jun 15, the insecticides were applied in 40 gal of water/acre with a 2-row portable boom CO2hand sprayer with 4 (TeeJet AL80015) nozzles spaced 17 inches apart. The potato plants were 12-14 inches high and the plants were naturally infested with Colorado potato beetle (CPB) at the time of insecticide application. Each treatment was replicated 2 times in a randomized complete block design. On Jun 16 (20 hours after treatment) 10.8 ft2 of soil surface between the 2 treated rows at each of 2 locations in each plot was searched, and the number of dead and live CPB adults and larvae on the soil were counted. On Jun 16 (20 and 24 h after treatment), and on Jun 19 (96 h after treatment), the potato plant foliage on 10.8 ft2 at each of 2 locations in each plot was examined, and the number of adults and larvae on the plants were counted. The percent control was calculated for each plot by Abbott’s Formula based on the number of live CPB found on the soil surface and the plant foliage per plot in the untreated and treated plots.

Abstract
‘Norchip’ Irish potatoes were planted with 10-inch plant spacing in 36-inch rows on Apr 8. Each plot consisted of a single, 25-ft-long row bordered on each side by an untreated row. The treatments were replicated 4 times in a randomized block design. The sprays were applied with a propane compressed air backpack sprayer using 3 hollow cone nozzles/row and delivering 75 gal water/acre at 40 psi. Applications were made on May 26, Jun 2, 9, 16 and 23. Yields were taken on Jul 20. Evaluation criteria consisted of direct counts of the number of Colorado potato beetle larvae/10 hills and late season foliage injury ratings. Foliage injury ratings were on a scale of 0-5 as follows: 0) no damage; 1) slight feeding, less than 5% defoliation; 2) visible feeding with 5-10% defoliation; 3) moderate damage, 10-25% defoliation; 4) heavy damage, 25-50% defoliation; 5) severe damage, greater than 50% defoliation.

Abstract
‘Superior’ potatoes were planted on May 5 in Sunderland, MA. The soil type was a fine sandy loam with a pH of ca 5.5. Dinoseb was applied at 2 lb ai/acre prior to plant emergence. Treatment blocks were replicated 4 times in a randomized complete block design. Each block consisted of two 30-ft rows with a 3-ft fallow area between each plot. Temik was applied directly to the seed furrow at planting with a Gandy applicator (Line Tender Model). Foliar treatments were applied with a 3-gal stainless-steel backpack sprayer and a CO2pressurized sprayer at ca 50 psi with a delivery rate of 65 gal/acre. Foliar spray applications were made on Jul 1, 8, 23 arrd 30, except for the biweekly applications of MK-936 0.03SL, which were made on Jul 1 and 23 only. On Jul 23, FMC 63429 was accidently applied to the FMC 54800 plots. Subsequently, FMC 63429 was applied at the new rates listed in the table below to the plots originally assigned to the FMC 54800 plots and FMC 54800 was applied at the 0.06 rate to the plots originally assigned to FMC 63429. Since this change in applications occurred between the 1st and 2nd generation of CPB, the resulting data should be comparable. Insect counts were analyzed using DMRT at the 5% level. Since, with few exceptions, all treatments were shown to be significantly different from the control, or, in the later counts, the control plots were 100% defoliated, the Duncan’s Test was applied to the insecticide treatments alone (without the control) to give a better indication of the relative effectiveness of the various insecticides.

Abstract
The test area was a 2-year-old stand of ‘Buffalo’ variety alfalfa. The plots were 34 x 36 ft and each treatment and the untreated control were replicated 3 times in a completely random design. Sprays were mixed so as to apply the proper rates in 20 gal of total volume per acre. Treatments were applied with a low-pressue, low-volume, Hahn field sprayer equipped with 21 Spraying Systems 8003 Tee Jet nozzles and operated at a pressure of 35 psi. Population densities of larvae were determined 3, 6, 14, 17 and 20 days following treatment by collecting 10 sweeps from each plot with a standard 15-in dia beating net. A damage rating was made on May 20 and was based on a scale of 1-9 where 1 = no damage and 9 = 100% of leaves consumed, with 2-8 being intermediate. The Bay Sir 8514 25WP treatments were applied Apr 1 with the remainder of the treatments being applied Apr 30. Treatment means, expressed as larvae per 10 sweeps on the sampling date indicated, were separated by use of Duncan’s New Multiple Range Test. A standard treatment of Furadan 4F was applied at the rate of 0.5 lb ai/acre.

Abstract
Rootworm planting-time, soil-insecticide test plots were established at 6 Iowa Locations in 1981. The experimental design for these tests was a randomized complete block design with 4 replications for the root-protection trials and 12 replications for the yield trials. The Ames, Nashua, Newell, and Red Oak root-protection trials had 50-ft, single-row treatments and were planted on May 5, 11, 7, and 6, respectively. The Alta and Marengo trials had 100-ft, 2 row treatments and were planted on Apr 29 and May 8, respectively. All yield trials had 50-ft double-row treatments. Granules were applied as in-furrow or 7-in band treatments with laboratory-calibrated Noble metering units mounted on a 4-row, Model 71 John Deere planter. Liquids were banded with a single-row sprayer mounted on the planter. All materials were applied in front of the press wheels and incorporated with drag chains. Rootworm feeding was evaluated by digging 5 roots from each treatment row and rating the damage on the Iowa 1-6 scale. Yields were determined by combining 1/200 acre in each rep at Ames and Nashua and hand picking 1/500 acre in each rep at Newell. Data were then converted to bu/acre of No 2 shelled corn at 15.5% moisture.
