Control of Resistant Colorado Potato Beetles, Andover, Mn, 1994
Authors: Noetzel David M. , Miller Jennifer 
Published: December 2017

Abstract
The trial was located near the 1993 trial in this area. Soils were of a muck, or high organic matter, type and were not irrigated. Soil treatments were made 24 hr post plant (6 May). Plots were 4 rows 25 ft. in length. Treatments were arranged in an RCB design, replicated 4 times. Planting ridges were opened, Admire 2F in 20 gal total material applied near the seed pieces, and covered to seeding depth. Soil moisture was excellent. Foliars were broadcast in 20 gal total material on 14, 21, 28 June; 6, 12, and 19 July. 2nd generation adults began to appear the 3rd week of July and plant decline proceeded quickly thereafter. Twenty foot sections of row were hand dug and weighed for yields.
Control of Resistant Colorado Potato Beetle, Blaine, Mn, 1995

Published: December 2017

Abstract
A trial was established in a commercial potato field following an initial application of Provado 1.6F at a rate of 0.31 lb (AI)/acre across the entire field. Plots were 4 rows X 25 ft in length, treatments were arranged in a RCB design, and replicated 4 times. Insecticide was applied on 1, 10 and 18 July in approximately 20 gal total material/acre using a hand held CO2 sprayer with 40 psi. Trigard was applied alone twice followed by the second insecticides. Very high populations of adult beetles continued to migrate into the plots leading to an unusually large variation in defoliation readings. Larval ratings were 0 = no larvae to 5 ≥ 100 larvae per plant. Late non-random weed pressure did not permit obtaining yields.

Abstract
This experiment was conducted in 4 miniblocks, each ⅓ acre, of 15-yr-old trees on M 7A rootstock. Trees measured 16.5 ft. in height and 16 ft. in width and were planted at a spacing of 20 X 20 ft. The experimental design consisted of half a miniblock (18 trees) for each of 6 spray treatment combinations and an entire miniblock for the untreated plot. Insecticides were applied as complete sprays to both sides of the tree with a Swanson DA500A airblast sprayer, which traveled at 2.3 mph and delivered a spray volume of 100 gpa. Dates (stage or degree-days after first trap catch of spring CM) of application were 11 Apr (tight cluster), 18 Apr (pre-pink), 12 May (petal fall), 26 May (273), 5 Jun (405), 8 Jun (462), 13 Jun (548), 22 Jun (696), 6 Jul (987), 18 Jul (1249), 1 Aug (1601), 16 Aug (1942), and 1 Sep (2225). Other materials applied separately to all treatments were Dithane, Kocide, K-salt (NAA), Nova, Penncozeb, Rubigan, Topsin-M, and Ziram. Treatment effect was evaluated by counting insects and injury on the periphery of 4 single-tree replications in the center row(s) of each plot periodically during the season. Control of SA was evaluated by counting aphids on the most infested leaf on each of 10 terminals/tree. WALH and RLH control was evaluated by counting nymphs on the underside of 25 leaves/tree. Control of CM and OFM was determined by counting injured apples during a 5 min period/tree. Treatment effect against STLM was determined by counting tissue-feeding mines observed during a 5 min period/tree. Control of fruit-feeding insects was determined at harvest by scoring for injury 100 picked apples/replication plus up to 100 drop apples/replication on 19 Sep.

Published: December 2017

Abstract
Eight treatments were evaluated to control melon thrips in potatoes planted on 9 Jan. Treatment plots, four rows by 25 ft, were arranged in a RCBD with four replications in a commercial potato field in Homestead, FL. All cultural practices for growing potatoes were as recommended. Treatments were applied weekly on four dates between 20 Feb. and 31 March 1995. Foliar applications were made by a backpack sprayer with two nozzles per row at 40 psi delivering 50-100 gpa depending on the volume of plants. Furadan, Diazinon and Admire were applied in a band in a 4 inch deep furrow 4 inch apart from the seed row 3 weeks after planting. All treatments were compared with a nontreated check. Insecticides were evaluated by randomly collecting 10 mature leaves, 1/plant, from the two center rows. Samples were collected 24 h after each foliar application. Leaves were washed with 70% ethanol to separate adult and immature thrips.

Abstract
Potatoes were planted in two fields on 15 March at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. One field was planted in the short season cultivar ‘Superior’, the other field in the long season cultivar ‘Snowden’. Plots in both fields consisted of 4 rows 25ft long on 3ft row spacing with 6ft of bare ground between plots. Treatments in both fields were applied in furrow prior to planting with a single nozzle boom backpack sprayer. Treatments were replicated 4 times in a RCB design. Foliar sprays (rates, dates and materials indicated in tables) were applied by a tractor-mounted sprayer delivering 40 gal water/acre at 100 psi. Spray decisions were based on the following CPB thresholds, determined by weekly counts on 10 randomly chosen stems/plot: 4 small larvae, 1.5 large larvae, or 0.5 adults/stem. Dates and life stages with significant differences are listed in the tables. Secondary pests on 10 randomly picked compound leaves/plot and percent defoliation were sampled on the dates indicated in the tables. Both fields were sprayed on 2 June with Monitor 4EC (lqt/acre) to control European corn borer.

Published: December 2017

Abstract
Experimental plots were established on the UI Research and Extension Center, Kimberly, Idaho. Potatoes were planted on 25 Apr and irrigated by solid set sprinkler. The soil type was Portneuf silt loam. Four treatments and one untreated check plot were replicated four times in a RCB design. Individual treatment plots were 4 rows (36 inch row spacing) wide by 25 ft long with 5 ft alleyways separating the plots. Green peach aphids were mass reared on greenhouse sweet pepper plants (California Wonder) for release into individual plots. Aphid releases were made into test plots the last wk in Jun and again in the first wk of Jul. A total of four heavily infested pepper plants was released per plot. Treatment sprays were broadcast applied using a CO2 pressurized backpack sprayer (30 psi) and delivering 20 gal finished spray per acre (four, 10X hollow cone nozzles). Aphid counts were made from non-destructively examining 10 randomly selected leaves in the center two rows of each plot. Leaves were sampled from the top, middle, and bottom sections of the plants. The data collected and presented are the total number of aphids per 20 leaves. On 19 Jul a pre-count was taken and on 21 Jul all treatment applications were made. Data were analyzed using ANOVA and Student-Newman-Keuls multiple means comparison.

Abstract
Standard and NewLeafR (NatureMarkR, producing Bacillus thurin-giensis subsp. tenebrionis 8-endotoxin) potatoes were planted 11 May at the University of Minnesota Agricultural Experiment Station, Rosemount, MN. Plots were each 8 rows by 50 ft and separated from other plots by 10 ft of soybean border. Treatments were arranged in a RCB design with 4 replications. Admire 2F was applied in-furrow at planting prior to closing the seed bed by using a CO2 pressurized sprayer, delivering 60 gal/acre at 35 psi. All other spray applications were made by using a tractor-mounted boom sprayer with 3 nozzles per row, delivering 60 gal/acre at 90 psi. Threshold of 30% egg hatch was used to initiate Novodor applications. Novodor as required treatments were applied at presence of &lt;80 small larvae (1st and 2nd instars). Orthene 75S was used to control green peach aphid on selected treatments. Late blight control was achieved by 5 spray applications of Bravo 500 (1 pt/acre) on 28 Jun; 7, 13 and 29 July; and 8 Aug, and 3 applications of Ridomil/Bravo 81WP (1 lb/acre) on 20 Jul; 2 and 18 Aug. Malathion 57EC (0.5 pt/acre) was used to control potato leafhoppers on 12, 29 July; 2 and 16 Aug. CPB egg masses, small larvae, large larvae (3rd and 4th instars) and adults were counted on 10 whole plants per plot on 23, 27 June; 3, 10, 18 and 26 July; 2, 8, 14, 23 and 29 Aug. NewLeafR potatoes provided season long commercially acceptable control of all CPB life stages. Fewer egg masses were laid on NewLeafR potatoes than other treatments. No small or large-larvae were found indicating that none of the neonates survived. Significantly lower numbers of CPB adults were observed on NewLeafR potatoes.

Abstract
Potatoes were planted 15 May at the University of Minnesota Agricultural Experiment Station, Rosemount, MN. Plots were 1 row, 25 ft long, and separated from other plots by 6 ft of fallow. Treatments were arranged in a RCB design with 4 replications. Treatments for GPA control were applied on 9 Aug, except for Admire 2F which was applied in-furrow at planting prior to closing the seed bed. All spray applications for GPA were made using a CO2 pressurized sprayer fitted with a Teejet 8003-E flat fan nozzle, delivering 60 gal/acre at 35 psi. Late blight control was achieved by 5 spray applications of Bravo 500 (1 pt/acre) on 28 Jun; 7, 13 and 29 July; and 8 Aug, and 3 applications of Ridomil/Bravo 81WP (1 lb/acre) on 20 Jul; 2 and 18 Aug. One application of Novodor (3 qts/acre) was targeted against Colorado potato beetle (CPB) at 30% egg hatch on 17 June. Asana 0.66XL (9.6 fl oz/acre) applications were applied on 22 and 28 June; 12 and 29 Jul to enhance GPA populations for the purpose of this test. Asana treatments also controlled CPB and potato leafhopper. Samples of 10 lower leaves were taken from the center plants in each plot and GPA were counted. GPA counts were made on 10, 17, and 24 Aug; 1, 7 and 14 DAT respectively.

Abstract
Sweet potatoes were transplanted on 19 Jun at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of 3 rows 20 ft long, planted on 3 ft row spacing. Each plot was separated from each other by an untreated guard row. Treatments were replicated 6 times in a RCB design. Mocap band treatments and the initial foliar sprays were applied with a single nozzle boom backpack sprayer. Temik was applied using a hand-held shaker. The broadcast treatments and the later foliar sprays were applied with a backpack sprayer using 6 flat fan nozzles/row delivering 21 gal water/acre for the broadcast treatments and 42 gal water/acre for the foliar sprays. Mocap treatments were applied on 25 May to avoid phytotoxicity. Regent foliar sprays were applied on 7 and 21 Jul. Sevin schedule foliar sprays were applied weekly from 7 Jul until 24 Aug. The Sevin threshold sprays were applied on 7, 14, 21, and 27 Jul to coincide with the peak flights of click beetles (adult wireworms), as determined by the black light trap at Painter, VA. On 11 Oct, the center row of each 3 row plot was harvested and 25 market sized roots were randomly selected, washed, and evaluated for insect damage.

Abstract
Six-week-old transplants were set on 15 June at the Mountain Horticultural Crops Research Station, Fletcher, NC. Plants were set 2 ft apart within 20 ft rows and rows were on 10 ft centers. Single-row plots were arranged in a RCB design with four replications. Materials were applied on 19 and 29 July, 7, 14, 21, and 30 Aug and 6, 13 and 21 Sept with a tractor-mounted boom sprayer delivering 50–100 gpa (gpa increased as plants grew) through 7 hollow cone nozzles per row (three nozzles on each side and one overhead). Powdered milk was added to all GemStar treatments at a rate of 4 lbs/acre. Treatments targeted specifically at lepidopterous larvae (All GemStar and Biobit treatments) received Provado 1.6F at 3.75 oz./acre on 29 July, 14 and 30 August, and 13 Sept for PA and SB control. Starting on 30 Aug, all GemStar treatments also received CGI-9501 (celery looper virus formulation) at 6.75 oz./acre for CL control. PA populations were monitored on 11, 20 and 25 July, 1, 11, 16 and 22 Aug by observing 10 leaves (3rd most recently expanded leaf) per treatment and recording the number infested with ≥ 1 apterous aphid. The lepidopterous larval complex (TFW, CL, SAW, YSAW) was surveyed using a beat-cloth method on 28 Sept and the total larvae found on all ten plants in three replications was recorded. Fruit was harvested on 16, 21 and 28 Aug and 5, 11, 18 and 25 Sept and those damaged by the lepidopterous larval complex (LEPS), and SB were recorded. All data were analyzed using a two-way ANOVA, and means were separated by using LSD (P=0.05).

Abstract
Three insecticide treatments were evaluated against PLH in a firstyear stand of ‘Haymaker ’ alfalfa located in Montgomery Co., VA. Plots of 24 X 40 ft were arranged in a RCBD with an untreated check in each of 4 replications. Mean alfalfa stem height and PLH density were estimated in each plot prior to spray treatment (21 Jul). Potato leafhopper density was estimated using combined counts of PLH nymphs and adults from 10 pendulum sweeps of a 15-inch diam sweep net taken arbitrarily across the plot. All insecticide treatments were applied as foliar sprays on 21 Jul using a CO2 backpack sprayer, delivering 20 gpa at 40 psi. Post-treatment alfalfa stem height and PLH densities were sampled every 3 to 4 d in each plot until harvest (14 Aug). Yields were determined from 60 ft2 swaths taken from each plot using a sickle-bar mower. Freshly mowed alfalfa was raked into a pile and weighed by hand using a milk scale to determine the wet wt at harvest. A 2.2-lb subsample of alfalfa was removed from each plot and dried at 131 to 140°F for 48 h to determine % dry matter. Forage samples were submitted to Virginia Tech Forage Testing Laboratory, Blacksburg, VA, for quality analysis, including % crude protein and % acid detergent fiber. A twoway ANOVA with Fisher ’s protected LSD was used to analyze differences among treatments in PLH sweep net counts (after [x + 0.5 ½ transformation), stem ht, dry matter yield, % crude protein, and % acid detergent fiber.

Abstract
Plots were established at the University of Idaho Plant Science Farm, Moscow, ID. ‘IMC-144’ Canola seed, supplied by Intermoutain Canola, was planted at 6 lb/acre using a 6-row (7 in spacing), small-plot, cone seeder on 19 May. Plots were 8 X 16 ft arranged in a RCBD with each treatment replicated 4 times. The plots were cultivated, harrowed and fertilized (200 lb/acre 40-0-0-6 and 150 lb/acre 16-20-0) prior to planting. Treatments were applied 31 May using a CO2-pressurized backpack sprayer equipped with 80° fan nozzles on a 6-ft boom that delivered 20 gpa at 30 psi. Flea beetle damage ratings, beetle densities, and counts of all plants in 3.3 ft of rows 3 and 10 (of 12) were made 3 and 8 d following the foliar applications. Damage to cotyledons was scored using a 0-6 rating system. Plots were harvested 22 Sep with a small-plot combine (4.6 ft header). All data were subjected to analysis of variance. To control late season aphid infestations, Capture 2EC (0.04 lb[AI]/acre) and Thiodan 3EC (1.0 lb.[AI]/acre) were applied 6 and 24 Jul, respectively.
