Embodiment 1
[0018] Spray clear water, 0.3% gossypol acetate, 0.6% gossypol acetate, 1.0% gossypol acetate, 0.04% spirotetramat, 1% gossypol acetate + 0.04% spirotetramat for comparison test, the results are as follows:
[0019]
[0020] It can be seen from the above table that after mixing, the control effect can reach 93.6%, and the effect is obvious.
Embodiment 2
[0022] A method for the prevention and control of mirid bugs. Mix gossypol acetate with a mass fraction of 0.7% and spirotetramat with a mass fraction of 0.035% evenly according to the volume ratio of 1:1, and choose to carry out from the outer periphery to the inner periphery when the sun just comes out. spray.
[0023] The solvents of gossypol acetate and spirotetramat are water, and the time of spraying is when the sun just rises, from the periphery to the inner periphery in a spiral manner, and the spraying amount is 12.5kg of mixed solution per mu of land.
[0024] When preparing spray medicine, add water-soluble foliar fertilizer at the same time, add water-soluble foliar fertilizer, the mass fraction of the added water-soluble foliar fertilizer is 13%.
[0025] Before spraying, pre-fertilize when planting. When fertilizing, mix the fertilizer with gossypol acetate, spirotetramat, and water according to the mass ratio of 400:1:0.2:15, and then evenly sprinkle it on the l...
Embodiment 3
[0027] A method for the prevention and control of mirid bugs. The gossypol acetate with a mass fraction of 0.6% and the spirotetramat with a mass fraction of 0.039% are evenly mixed according to the volume ratio of 1:1, and the selection is carried out from the outer periphery to the inner periphery when the sun just comes out. spray.
[0028] The solvents of gossypol acetate and spirotetramat are water, and the time of spraying is when the sun just rises, from the periphery to the inner periphery in a spiral manner, and the spraying amount is 13.5kg of mixed solution per mu of land.
[0029] When preparing spray medicine, add water-soluble foliar fertilizer at the same time, add water-soluble foliar fertilizer, the mass fraction of the added water-soluble foliar fertilizer is 13%.
[0030] Before spraying, pre-fertilize when planting. When fertilizing, mix the fertilizer with gossypol acetate, spirotetramat, and water according to the mass ratio of 350:1:0.2:17, and then even...
