Embodiment 1

[0023] Weigh 30 g of pyrenpyrad and spinosad, 4 g of calcium dodecylbenzenesulfonate, 4 g of phenethylphenol polyoxyethylene ether, and 100 g of vegetable oil. Put the above raw materials into a mixing tank according to the conventional method for preparing emulsifiable concentrate, and mix them to prepare pyrenpyrid-ethyl spinosad emulsifiable concentrate with a main active ingredient of 30% by weight. Wherein the specific ratios of pyrenpyrad and spinosyn are shown in Tables 1 and 2.

[0024] Indoor synergistic bioassay was carried out by feed poisoning method, the resistant cotton bollworm was selected as the target pest, each treatment was repeated 3 times, and 60 heads were treated at each concentration, and the toxicological regression equation and sum of each pesticide resistant cotton bollworm were calculated by the probability value method lethal middle concentration LC 50 , with LC 50 The co-toxicity coefficient was calculated according to Sun Yunpei method, and th...

Embodiment 2

[0034] Weigh 5g of pyrenpyramid, 50g of spinosad, 3g of tristyrylphenol polyoxyethylene ether phosphate, 2g of Nongru 33#, 1g of 600#, 13g of solvent oil, and add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing water-based emulsions and mix at high speed to form a tonamiprole-spinosyn water-based emulsion with a main active ingredient weight percentage of 55%.

Embodiment 3

[0036] Weigh 2g of pyrenpyrad, 18g of spinosad, 6g of calcium dodecylbenzenesulfonate, 3g of tristyrylphenol polyoxyethylene ether phosphate, 2g of agricultural milk 33#, 1g of 600#, cyclohexanone 10g, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing microemulsions and mix them to form a tonamiprole-spinosyn microemulsion with a main active ingredient of 20% by weight.

[0037] Carry out control cotton bollworm drug effect test to embodiment 3, contrast agent is 60 grams per liter of spinosad SC and 15% tolfenpyrad SC, dilute according to the dilution factor in table 3, check 3 days after medicine, 7 Day, the result of 14 days, the processing result is shown in Table 3:

Abstract

The invention discloses a compound insecticidal composition containing tolfenpxrad and spinetoram and an application of the compound insecticidal composition. The insecticidal composition takes tolfenpxrad and spinetoram as insecticidal active ingredients, wherein the weight ratio of tolfenpxrad to spinetoram is (0.1-80):(0.5-80). The insecticidal composition can generate a relatively high synergistic effect, overcomes and delays the harmful insect resistance, is high in insecticidal speed and long in lasting period, and reduces the drug cost, and the control effect of the insecticidal composition is obviously higher than that of a single agent. The insecticidal composition disclosed by the invention can be used for controlling lepidopterous pests, in particular cotton bollworm and stem borers, on crops, and the effect of the insecticidal composition is obviously higher than that of a single agent.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides containing heterocyclic compounds, and in particular relates to a compound insecticidal composition containing tolfenpyrad and spinosad and its application. Background technique [0002] Fenpyrad (Tolfenpyrad), chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy)phenyl]-methyl}-1H pyrazole -5-carboxamide, molecular formula: C 21 h 22 C l N 2 o 2 , the structural formula is: [0003] [0004] Fenpyramid is a new type of pyrazole heterocyclic insecticide and acaricide developed by Mitsubishi Chemical Corporation in Japan. Its main mechanism of action is to prevent the oxidative phosphorylation of insects, and it also has the functions of killing eggs, inhibiting feeding, inhibiting oviposition and bactericidal effect. [0005] Spinetoram, the structural formula is: [0006] [0007] XDE-175-J is a new spinosad insecticide produced by Dow AgroSciences and has receive...
