Abstract
‘Russet Burbank’ potatoes were planted April 16 in Ritzville silt loam soil at Yakima, Washington. Plots were 2 rows wide, 34 inches (86 cm) apart and 50 ft (15.2 m) long. Each treatment was replicated three times in a randomized complete block design. On June 1, when about 75% of the plants had emerged, sidedress applications of granular materials were applied with tractor-mounted Gandy applicators. These granules were placed in 1-inch (2.54-cm) bands, 4 inches (10.2 cm) to each side and at about the same depth as the potato seed pieces. On the same date, topical applications of granular materials were made by using a funnel-type, hand-operated applicator. These granules were placed in 6-to 8-inch (15- to 20-cm) bands over the tops of the small potato plants and then mixed into the soil with a Lilisfon cultivator. The crop was sprinkler irrigated immediately following the treatments. Aphid populations were determined by collecting 20 compound potato leaves from the lower two-thirds of the plants from each plot on June 8, 18, July 8, and August 3. Visual ratings of the damage (0 = no damage and 10 = plants destroyed) done by the Colorado potato beetle were made in each plot on August 12, 19, 26, and September 2. The data were subjected to analysis of variance and Duncan’s multiple range test.

Abstract
‘Russet Burbank’ potatoes were planted in furrows on April 20, 1977, in Ritzville silt loam soil at Yakima, Washington. Plots were 2 rows wide, 1.72 m, and 15.2 m long. Furrow applications of granular insecticides were made by dribbling the materials through a hand-operated, funnel-type applicator over still uncovered potato seed pieces; then the seed pieces were covered with soil. Sidedress applications were made June 3, when about 75% of the plants had emerged; these applications were made with a tranctor-mounted Gandy applicator in about 5-cm bands, 10 cm to each side of the plants and about the depth of the potato seed pieces. Topical applications were also made June 3 but with a hand-operated applicator in about 25-cm bands over the top of the emerging potato plants; then the granules were lightly incorporated into the soil with a Lilliston cultivator. Each treatment was replicated 3 times in a randomized complete block design. The crop was sprinkler irrigated: 38 cm of water was applied between May and September. Aphid counts were made from 20 compound potato leaves in June and from 15 such leaves in July. The percent of plants damaged by the Colorado potato beetle was recorded on July 7, 18, and August 19. The data were subjected to analysis with Duncan’s Multiple Range Test.

Abstract
Experiments A, B, C, D, and E were 7x6, 7x6, 8x6, 7x6, and 6x6 randomized complete block designs respectively and were conducted at Presque Isle, Maine, on land that was sown to oats in 1976. The planting date was May 25, 1977, 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 M45 (1121 g/ha week of July 17 and 1781 g/ha weeks of July 24 through August 28, 1977). Soil applications of insecticides were made by hand with a plastic tube applying previously weighed amounts of insecticide into the furrow fust prior to planting. Foliar insecticide applications were made with a Slosser sprayer (14.1 kg/cm2 and 1.2 kl/ha). Foliar insecticides were mixed with the fungicide.
Potato, Wireworm and False Wireworm Control, Echo, Oregon, 1977
Authors: Toba H. H. , Turner J. E. 
Published: March 2022

Abstract
The test was conducted in a grower’s center-pivot, sprinkler-irrigated field. The soil type was Ritzville (Calciorthidie Haploxerolls) silt loam; it contained less than 0.5% organic matter. Soil samples (150) taken in a similar adjacent field with a 51/2-in. diam posthole digger to a depth of at least 18 in. gave 12 Great Basin wireworms and 40 false wireworms. Each plot measured 50-ft long and 6-rows wide (34-in. apart), and each treatment was replicated 4 times in a randomized complete block design. The materials, all granular formulations, were broadcast Apr 1 with a hand-operated grass seeder and disced to a depth of 4-6 in. within 1 h after application. The seed pieces were planted Apr 2 by the grower. On Aug 29, tubers were obtained from rows 2 and 5 of each plot (15 ft/row). All were washed and examined, and the percentages, by weight, of injured and culled tubers were determined. “Injured” was defined as any penetration of a tuber by wireworms or false wireworms and “culled” was defined as any injury severe enough to meet the description of “damage” in Sec. 51.1554 of the U. S. Standard for potatoes. The percentages were transformed to arcsine and analyzed by analysis of variance and Duncan’s multiple range test. All of the treatments produced significantly fewer injured and culled tubers than the check.

Published: March 2022

Abstract
Field plots were located on a sandy loam soil with treatments replicated four times in a randomized complete block design. Three-row plots, 5-ft apart and 20-ft long were planted at 12-inch spacing on May 12. Granular systemic treatments were banded 2-inches deep, 6-inches from the plants on both sides of the row on Jun 2. Foliar treatments were initiated Jun 20 and repeated 5 times Jul 6, 18, 27, and Aug 4 and 21. A tractor-mounted boom sprayer equipped with drop nozzles on either side of the row and one nozzle over the center delivered 66 gal/A at 300 psi. Control data for aphids and Colorado potato beetles are reported for the Jul 10 evaluation date. Aphid populations were determined by counting the number present on 10 randomly selected leaves from each plot. Colorado potato beetle counts represent the mean number of both adults plus larvae per 20 ft of row. Cabbage looper activity was indexed Aug 28 by recording the evidence of looper feeding holes present on 10 randomly selected leaves per plot. Tomatoes were harvested twice on Aug 15 and 28.

Published: March 2022

Abstract
Test materials were applied to apple trees at Monomouth, Maine, as dilute sprays with a hand gun from a hydraulic sprayer operating at 300 psi. In Test 1, 28-yr-old trees were sprayed at a rate of ca. 250 gal/acre; in Tests 2 and 3, 13-yr-old apple trees were treated at 500 to 600 gal/acre. Spray dates were Jun 23 and Jul 3 (Test 1), Jun 26 and Jul 3 (Test 2), and Jul 20 and Aug 16 (Test 3); each material was applied on both dates for the respective tests. The fungicide and insecticide program during the course of these acaricide tests consisted of captan 80W (1.25 lb/100 ga I) on 4 dates; Imidan 50W (1.25 lb/100 gal) on Jul 5, 17, and Aug 2; Thiodan 50W (.5 lb/100 gal) on Jul 11 and 17; and Sevin 80W (1.25 lb/100 gal) on August 15. There were no tank-mixtures of acaricides with other pesticides. There were 4 single-tree replications per treatment. A randomized, complete-block design was utilized with 2 Golden Delicious and 2 Red Delicious cultivars per treatment in Tests 1 and 3 and 2 Cortland and 2 Mcintosh per treatment in Test 2. From each tree, 25 leaves were collected mostly at chest-height around the periphery of the tree, brought into the laboratory, and brushed onto glass plates coated with a Tween 20-alcohol mixture; mites were counted the same day. Mite population pressure was heavy in August. On the prespray date, egg populations ranged from 4 to 8 eggs/leaf (Test 1), 1 to 2 eggs/leaf (Test 2), or 15 to 30 eggs/leaf (Test 3). July and August were very dry and hot months.

Abstract
For this test conducted at Agway Farm Research Center, Fabius, NY, seeds of Provider Greenhouse snapbeans, Fordhook 242 lima beans, California light red kidney beans, and Pioneer 334S field corn were treated with Insecticides or insecticides and fungicides; exception to this was soil application of in-furrow Temik 15G. For small plot testing, 100 seeds per treatment were treated on Jun 17‘77, using a randomized block design and 3 replications; plot size was 11' x 20' using 4-rows per plot, 1 row for each variety tested - row spacing was 36-inches. A screen cone fly trap was used to time planting date for the appearance of second brood seed maggot adults. In addition, 100 lbs/plot of Corenco blood and bone meal was banded over the top of planted rows to attract adults to the test site to insure oviposition. Thirty seeds of each variety were hand planted on Jun 17‘77 per 20' of row. Respective amounts of insecticide or insecticide-fungicide hopper box seed treatments were placed with the seed in kraft paper bags and shaken to thoroughly coat the material on the seeds. The treatment of Dursban 4E (M-4170) + Captan 50W was applied at the rate of 2 oz + 2 oz of product/100 lbs of seed as a slurried seed dressing. On Jul 14‘77, the plant stands were counted along with determining the degree of seed maggot injury to emerged seedlings.
