Embodiment 1

[0022] Weighed spinosad and spirotetramat and formulated them in different proportions according to conventional preparation methods to prepare spinosad and spirotetramat emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 1 for specific proportions.

[0023] The toxicity of ethyl spinosad, spirotetramat and their compound samples to cotton bollworm was determined by feed poisoning method, each treatment was repeated 3 times, and 30 heads were treated at each concentration, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0024] Table 1 Toxicity determination and co-toxicity coefficient of spinosad, spirotetramat and their compound samples to cotton bollworm

[0025]

[0026] Data in the table shows that after the mixing of spinetoram and spirotetramat, there is a synergistic effect on cotton bollworm, and the co-toxicity coefficients of the four ratios listed in the table are all greater than 120, s...

Embodiment 2

[0028] Weighed spinosad and spirotetramat and formulated them in different proportions according to conventional preparation methods to prepare spinosad and spirotetramat emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0029] The toxicity of spinosad, spirotetramat and their compound samples to rice brown planthopper was determined by rice stem dipping method, each treatment was repeated 3 times, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0030] Table 2 Toxicity determination and co-toxicity coefficient of spinosad, spirotetramat and their compound samples against rice brown planthopper

[0031]

[0032]

[0033] The data in the table shows that the mixture of spinetoram and spirotetramat has a synergistic effect on rice brown planthopper, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120, so spinetoram and ...

Embodiment 3

[0035] Weigh 5g of spinosad, 20g of spirotetramat, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and put the above raw materials into Mix in the mixing tank to form the ethyl spinosad spirotetramat emulsifiable concentrate whose main active ingredient is 25% by weight.

[0036] The sample that adopts embodiment 3 to carry out the field test of field control cotton bollworm in the field, contrast medicament is 60 grams per liter of ethyl spinosad SC and 24% spirotetramat SC, and concrete consumption is shown in Table 3, and the water consumption per mu is 30kg, check the results after 3 days, 7 days, 14 days, and 28 days after taking the medicine. The test results are shown in Table 3:

[0037] Table 3 Field test results of example 3 samples on cotton bollworm

[0038]

[0039] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on cotton bollworm, and has a relatively long duration of effect...

Abstract

The invention discloses a composite insecticidal composition containing spinetoram and spirotetramat and an application thereof. In the composite insecticidal composition, the spinetoram and the spirotetramat are employed as main active components, wherein a weight ratio of the spinetoram to the spirotetramat is 0.1-80:0.5-80. The composite insecticidal composition can achieve a prevention and treatment spectrum expanding effect and a synergistic effect, is reduced in application cost, can be prepared into emulsion oil, wettable powders, micro-emulsions, emulsion in water, suspending agents and water dispersible granules, and is used for preventing various pests comprising lepidoptera pests, hemiptera pests, hymenoptera pests, coleopteran pests and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with spinosad and spirotetramat as main active ingredients and an application thereof. Background technique [0002] Spinetoram, the structural formula is: [0003] [0004] XDE-175-J is a new spinosad insecticide produced by Dow AgroSciences and has received the first global registration, it can effectively control important pests on fruit trees and nuts, especially on fruit trees One of the thorny main pests of the apple moth. It is mainly used to control Lepidoptera larvae, thrips and leafminers, etc. It has good control effects on diamondback moth, beet armyworm, leafminer, thrips, Spodoptera litura and pod borer. [0005] Spirotetramat (Spirotetramat) chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5] - Dec-3-en-2-one. The structural formula is as follows: [0006] [0007] Spirotetramat is highly efficien...
