Control Insect

There exists a lack of control efficacy information to enable decision-making about which organic insecticide product works best for a given insect pest. Here, we summarize results of 153 field trials on the control efficacy of common active ingredients in organic insecticides against 12 groups of the most difficult to control insect pests. These trials evaluated primarily the organic products Entrust (spinosad), Azera (pyrethrin and azadirachtin), PyGanic (pyrethrin) and Neemix (azadirachtin), which reduced pest infestations by an overall 73.9%, 61.7%, 48.6% and 46.1% respectively, averaged across all trials. Entrust was the most effective control option for many insect pests, particularly providing >75% control of flea beetles, Colorado potato beetle, cabbageworms and alfalfa weevil, but was relatively ineffective against true bugs and aphids. Azera provided >75% control of green peach aphid, flea beetles, Japanese beetle, Mexican bean beetle, potato leafhopper and cabbageworms. PyGanic was less effective than Entrust and Azera but still provided >75% control of green peach aphid, flea beetles and potato leafhopper. The growth inhibition effects of azadirachtin in Neemix were particularly effective against larvae of Mexican bean beetle and Colorado potato beetle but was generally less effective in trials with insect infestations consisting mainly of adult stages. Those insect pests that were particularly difficult to control included thrips, stinkbugs, cucumber beetles and fruitworms. Several caveats pertaining to the application of the results are discussed.

Spray Applications

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.

And Control

The mechanisms of transmission of potato viruses from plants to aphid vectors and from aphids to uninfected plants are described, including the example of the green peach aphid (Myzus persicae, GPA). Factors affecting the spreading of tuber necrosis and its manifestation on plants infected with potato leafroll virus (PLRV) are discussed. Recommendations for PLRV and GPA control in the field are given.
