The synergistic effect of the acaricidal synergists obtained in examples 1 to 7 and comparative examples 1 to 2 is detected, and the detection method comprises the following steps:
the acaricide synergist obtained in the above examples 1-7 and comparative examples 1-2 is respectively mixed with acaricide (15% abamectin/etoxazole suspending agent) in a tank, and the mixing mass ratio of the acaricide synergist to the acaricide is 3: 4. When the acaricide is used, firstly, the acaricide is diluted by 1000 times by taking water as a medium, namely the concentration of the acaricide is 1g/L, then, a specific amount of acaricide synergist is added according to the mass ratio of the acaricide synergist to the acaricide before dilution of 3:4, and after uniform mixing, the acaricide is subjected to an efficacy test for preventing and treating strawberry red spiders.
The test site of the pesticide effect of the strawberry red spiders is in the urban area of the baoding city, and the strawberry red spiders are seriously damaged in the test area all the year round. The test was conducted in 11 treatment zones (including a control zone where no insecticide was applied, a zone where the acaricide was applied alone, 7 zones where the acaricide was applied with the synergist of examples 1 to 7, and 2 zones where the acaricide was applied with the synergist of comparative examples 1 to 2), which were repeated 3 times for a total of 33 test treatment zones, each zone having a size of 20m2Random block permutation is adopted. Investigating radix Aranea base of strawberry immediately before application, with application rate of 45ml/m2And 7d and 15d after application investigate the change condition of the quantity of the strawberry red spiders, randomly selecting 5 strawberries in each area for marking, directly observing the leaf surface by using a handheld magnifier, counting the quantity of the strawberry red spiders on the leaves, calculating the control effect of the strawberry red spiders, and calculating the control effect of the strawberry red spiders according to the following formula:
the strawberry red spider decline rate is (number of live strawberry red spiders before prevention and control-number of live strawberry red spiders after prevention and control)/number of live strawberry red spiders before prevention and control x 100%.
The control effect of reducing spider mites on strawberries is (strawberry spider fall rate in a treatment area-strawberry spider fall rate in a control area)/(strawberry spider count fall rate in a 100% -control area) × 100%.
