Abstract Peppers were transplanted on 31 Jul at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of two 25ft long rows with 3ft between row spacing and 1ft between plant spacing. Each plot was bordered on each side by an untreated guard row and replicated 4 times in a RCB design. Treatments were applied on the dates indicated in the table with a backpack sprayer using 3 hollow cone nozzles/row and delivering 60 gal water/acre at 40 psi. Evaluation criteria consisted of hand-harvest of marketable fruit on 10 healthy, uniform-sized plants/row (.00062 acre) and GPA counts on 5 randomly picked leaves/plot on 06 Oct. Harvesting was done in this manner due to uneven stands in some plots due to the drought.

Abstract Peppers were transplanted on 22 May at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of two 25ft rows, planted on 3ft row spacing. Plots were separated from each other by an untreated guard row. Each treatment was replicated 4 times in a RCB design. Treatments were applied with a 3 nozzle boom backpack sprayer delivering 60 gal water/acre at 40 psi. Treatments were applied weekly beginning 19 Jul through 16 Sep. The aphidicides CGA 215944 and Provado were added to the pyrethroid treatments indicated in the table on 1,8, and 16 Sep after GPA populations had built up. Spod X was added to the Pounce treatments on the last four application dates to control BAW. The gallonage was increased to 73 gpa for the last 3 applications due to the growth of the plants. Evaluation criteria consisted of hand-harvests of market sized fruits from the more uniform row of each 2 row plot on the dates indicated in the table. This fruit was graded to remove any ECB or BAW damaged fruit and the remaining marketable fruit was weighed to determine yields. Numbers of GPA on 5 randomly picked leaves/plot were counted on the dates indicated in the table.

Abstract Sweet potatoes were transplanted on 20 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. An untreated guard row separated each plot from each other. Treatments were replicated 6 times in a RCB design. In furrow and band treatments, and the initial foliar sprays were applied with a single nozzle boom backpack sprayer. Granular treatments were applied with a hand held shaker. The Mocap treatments were applied on 25 May to avoid phytotoxicity. The later foliar sprays were applied with a backpack sprayer using 6 flat fan nozzles/row and delivering 42 gal water/acre at 40psi. Thiodan sprays were applied on 7, 14, and 21 Jul. Sevin XLR was sprayed on 27 Jul in order to observe the restrictions on the number of applications allowed on the Thiodan label. Foliar sprays were applied in order to coincide with clickbeetle (adult wireworm) flights, as determined by the black light trap at Painter, VA. Layby treatments were applied on 26 Jul. 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 Tomatoes were transplanted on 9 Aug at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of a single row 20 ft X 5 ft, bordered on each side by an untreated guard row. On 1 Oct, heavy potato aphid populations developed in the test field. A pre-count of live aphids on 5 randomly picked compound leaves/plot was taken on this date and followed by a single application of all treatments. Treatments were applied with a backpack sprayer equipped with a 3 hollow cone nozzle boom and delivering 46 gal water/acre at 40 psi. To evaluate efficacy, the plots were sampled as previously described for the pre-count on the dates indicated in the table.

Abstract Wheat was planted on 2 Nov, 1994, at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Plots were 25 ft long by 5 ft wide, with 7 inch spacing between rows. Each plot was separated from each other by 3 ft of bare ground and replicated 4 times in a RCB design. Insect pressure from all species was low this year. Treatments were applied on 5 May using a propane compressed gas backpack sprayer with a 3 flat fan nozzle boom which delivered 20 gal water/acre at 40 psi. Evaluation criteria consisted of counts of insects present on 6 ft of row. EGA was the dominant aphid species with low numbers of BCOA present. Numbers of both species were analyzed together as a complex.

Spring Planting

Abstract Cucumbers were planted on 17 Jun and 12 Aug at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of 2 rows 25 ft long with 5 ft spacing between rows. Plots were separated from each other by 10 ft of bare ground. Treatments were replicated 4 times in a RCB. Prior to planting, the Admire and Furadan treatments were applied in furrow using a single nozzle boom backpack sprayer. The foliar sprays were applied with a 3 hollow cone nozzle boom backpack sprayer delivering 45 gpa at 40 psi. The Adios AG treatments were broadcast over the appropriate rows using a hand-held shaker on the same dates as the foliar sprays. Application dates were 18 and 24 Jul and 2 Aug for the spring planting and 30 Aug and 9 and 23 Sep for the fall planting. Evaluation criteria were: beetle counts on a 6 ft row section of each plot. Dates with significant differences are recorded in the tables. No attempt was made to obtain yield data, because the growth of the crop across the field was highly variable due to heavy rainfall, especially in the spring planting.

Abstract Tomatoes were transplanted into two fields on 27 Jul at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of a single 25ft row with 5ft between row spacing. Plots were replicated 3 times in a RCB design and separated from each other by untreated guard rows. The design in both fields was the same except for the number of treatments. Treatments were applied with a backpack sprayer using 3 hollow cone nozzles/row and delivering 45 gal waterlacre at 40 psi. Application dates for each field are indicated in the tables. Bravo 720 at 1.5pVacre was added to each treatment and the checks on 26 Sep and 02 Oct for disease control. On 9 Oct (Field I) and 16 Oct (Field 11). 25 green fruits were randomly picked from each plot and examined for worm damage.

Abstract Potatoes were planted on 27 March at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of 4 rows 25ft long, planted on a 3ft row spacing. Plots were separated from each other by 6ft of bare ground, and each treatment was replicated 4 times in a RCB design. Treatments were applied in furrow prior to planting using a hand-held shaker for the Regent 1.5G formulation and a single nozzle boom backpack sprayer for the other formulations. All CPB life stages on 10 randomly chosen stems/plot were counted weekly. Dates for which there were either significant differences or noticeable trends are recorded in the tables. Numbers of PLH nymphs on 10 randomly picked compound leaves/plot were sampled. Percent defoliation/plot was estimated on the indicated dates in the tables. On 12 July, the center two rows of each plot were harvested and graded to determine yields.

Abstract Snapbeans were planted on 18 May at the Eastern Shore Agricultural Research and Extension Center, Painter, VA. Each plot consisted of 2 rows 25 ft long and planted on 3 ft row spacing. Plots were bordered on each side by an untreated guard row. Each treatment was replicated 4 times in a RCBD. Granular treatments were applied in furrow prior to planting using a hand-held shaker. DiSyston and Thimet granules were manually incorporated to avoid direct contact with the seeds and phytotoxicity. The Orthene foliar spray was applied on 9 June, after the formation of the first trifoliate leaves, with a three-nozzle boom backpack sprayer delivering 60 gal water/acre at 40 psi. To evaluate efficacy, 10 trifoliate leaves/plot were randomly picked on the dates indicated in the table, washed in soapy water, and filtered through a Buchner funnel. Thrips and PLH nymphs were then counted under a stereoscopic microscope.
