    In: Insecticide and Acaricide Tests, Oxford University Press (OUP), Vol. 16, No. 1 ( 1991-01-01), p. 61-61
    Abstract: The plot was planted and treated 22 Jun at our research farm near Geneva, New York, in a Lima silt loam soil. Seeds (planted at 6/ft) and treatments were applied using a hand-pushed cone seeder. Germination counts were made 17 Jul. The crop was then thinned to ca. 1 plant every 15 inches. Plots consisted of a single row, 20 ft long, replicated 4 times in a randomized complete block. Insecticide applications were based on a 36 inch row width. All applications were made in the furrow with a gravity system mounted on the cone seeder which delivered 50 gal/acre. Injury ratings were made 29 Oct by pulling 10 roots/plot, washing them, and counting the number of tunnels present.

    Control of Cabbage Maggot on Turnip, 1978

    Abstract: Plots were planted and treated on Jun 15 with a single cone seeder. Seeds were planted at 10 seeds/ft, germination counts made on Jun 30, and emerged seedlings were thinned to ca. 2/ft on Jul 6. Each treatment consisted of a single row, 25-ft long, replicated 4 times in a randomized complete block design. Rows were 36-inches apart, but the insecticide treatments were based on a 24-inch row width since this is the most common row width used by crucifer growers in New York State. Foliar sprays were applied at 63 gallons HoO/acre on Jul 17 and Aug 18 with a single nozzle CO2_powered sprayer mounted on the single cone seeder. Soil type was a Lima silt loam. Turnip roots were pulled, washed and rated for injury by counting the number of tunnels on 10 roots/treatment on Sep 13.

    Abstract: The plot was planted and treated 1 Jul at our research farm near Geneva, New York in a Lima silt loam soil. Seeds (planted at 10/ft) and treatments were applied using hand pushed cone seeders. Germination counts were made 17 Jul. The crop was then thinned to ca. 1 plant every 15 inch. Plots consisted of a single row, 20 ft long, replicated 4 times in a randomized complete block. Insecticide applications were based on a 36-inch row width. In-furrow liquid applications were made with a gravity system mounted on a cone seeder delivering 50 gpa. Over-furrow applications were applied at 50 gpa to the soil surface after planting using a CO2 powered sprayer. Injury ratings were made 9 Oct by pulling 10 roots/plot, washing them, and counting the number of tunnels present. Extremely dry conditions (only .39 inch of rain from 1 Jun to 30 Sep) resulted in inhibition of both seed germination and soil insecticide activity.

    Onion Maggot Control, 1989

    Abstract: The plot was planted 20 Apr in muck soil near Potter, New York on Franjo Farms. Plots were single rows, 30 ft long, replicated 4 times in a randomized block design. Germination and damage data were recorded from the center 20 ft of each row. All seeds were sown and seed-furrow treatments of insecticides as well as entomogenous nematodes (Heterorhabditis and Steinernema) applied with a hand-pushed cone seeder planting nine seeds/ft and delivering 75 gal/acre through a gravity fed system. Insecticide band treatments were based on a 15 inch row width. Soil injection treatments of nematodes were applied at peak fly activity using a CO2 powered injection system delivering ca. 3950 gal/acre on a 15 inch row basis. Stand counts were taken 25 May. Maggot damage was assessed by checking each row for wilted plants ca twice/wk from the time of stand counts until 25 Jul.

    Abstract: Plots were planted Apr 14 in Elba and May 4 in Oswego. Both locations are mucklands of major importance to the onion industry in New York. Plots were single rows, 30-ft long, replicated 4 times in a randomized block design. Data was recorded from the center 20 ft of each row. All treatments were applied in the furrow with a hand-pushed cone seeder planting 9 seeds/ft and delivering 75 GPA through a gravity-fed spray system. Dithane M-45 (80 WP) was applied in the furrow with each treatment at 2.4 lb ai/acre for control of onion smut. Stand counts were taken May 29 at Elba and May 31 at Oswego. All drenches were applied in a 2-4 in band at the time of stand counts through a CO2-powered system mounted on a cone seeder delivering 75 GPA through one flat fan (8006) nozzle. Maggot damage was assessed by checking each row for wilted plants ca twice per week during Jun and early Jul. Each wilted plant was pulled and examined to determine whether injury was due to onion maggot or other causes. Harvests were taken Sep 4 at Oswego and Sep 11 at Elba by topping, pulling, counting and weighing the onions in each 20 ft row.

    Cabbage Maggot Control Using Dasanit 6E, 1978

    In: Insecticide and Acaricide Tests, Oxford University Press (OUP), Vol. 4, No. 1 ( 1979-01-01), p. 60-60
    Abstract: Treatments consisted of two 50-ft rows planted in blocks and replicated 4 times. Insecticide applications were based on a 24-inch row width because this is the row width most commonly used by cole crop growers in New York State. Seeds were planted with a tractor-mounted Stan-Hay 2-row precision seeder on Jun 7. The over-furrow sprays at planting time were applied in 63 gal. H2O/A through a PTO driven delivery system mounted on the tractor. A single flat fan nozzle (1510), rotated sideways to produce a 3-4 inch wide spray band over the closed furrow, was mounted on a bracket just above and behind each packer wheel. Seeds were planted at 15/ft and thinned on Jun 27 to 1 every 1.5 feet. Timed sprays for reduction of succeeding generations of cabbage maggot flies were applied to both crops on Jul 17 and to cabbage only on Aug 18. Delivery of these sprays was made through a PTO driven tractor-mounted 2-row sprayer with 3 flat fan (110015) nozzles/row at 55 gals. H2O/A. Damage assessments were made on Oct 4 by pulling 10 roots/treatment/replication, washing them, and counting the number of cabbage maggot tunnels in each root.
