Embodiment 1

[0022] Weigh spinosyn and nitenpyram and prepare spinosyn nitenpyram emulsifiable concentrate with a main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. See Table 1 for specific proportions.

[0023] The toxicity of spinosad, nitenpyram 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. 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

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

[0025]

[0026] Data in the table shows that after the mixing of spinetoram and nitenpyram, there is a synergistic effect on cotton bollworm, and the four proportioning co-toxicity coefficients listed in the table are all greater than 120, so spinetoram and nitenpyram The compounding of nitenpyram has ...

Embodiment 2

[0028] Weigh spinosyn and nitenpyram and prepare spinosyn nitenpyram emulsifiable concentrate with a main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. See Table 2 for specific proportions.

[0029] The toxicity of spinosad, nitenpyram 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, nitenpyram and their compound samples to rice brown planthopper

[0031]

[0032]

[0033] The data in the table shows that the mixture of spinetoram and nitenpyram 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 nitenpyram The compounding of nitenpyram has a signifi...

Embodiment 3

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

[0036] The sample that adopts embodiment 3 to carry out the field test of field control cotton bollworm in field, contrast agent is 60 grams per liter of spinosad SC and 10% nitenpyram AS, 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:

Abstract

The invention discloses a composite insecticidal composition containing spinetoram and nitenpyram and an application thereof. In the composite insecticidal composition, the spinetoram and the nitenpyram are employed as main active components, wherein a weight ratio of the spinetoram to the nitenpyram 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 containing spinosyn and nitenpyram 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] Nitenpyram is a new type of neonicotinoid insecticide, chemical name: (E)-N-(6-chloro-3-pyridylmethyl)-N'-methyl-2-nitro Ethylenediamine, molecular formula: C 11 h 15 ClN 4 o 2 , the structural formula: [0006] [0007] Nitenpyram ha...
