Example Embodiment

[0022] Example 1:

[0023] Weigh Methoxyfenozide and Spinosyn and use conventional preparation methods to prepare Methoxyfenozide·spinosyn EC in different proportions with the main active ingredient weight percentage of 30%. The specific ratios are shown in Tables 1,2.

[0024] Using leaf immersion method for indoor synergistic bioassay, select resistant diamondback moth as the target pest, repeat 3 times for each treatment, and treat 60 heads per concentration, calculate the toxicological regression equation and lethality of each drug resistant diamondback moth by probability value method Medium concentration LC 50 , Use LC 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient, and the results are shown in Table 1:

[0025] Table 1 Toxicity determination of methoxenozide and spinosyn and single dose of resistant diamondback moth

[0026]

[0027] It can be seen from Table 1 that the co-toxicity coefficient of the combination of methoxenic hydrazide and spinosy...

Example Embodiment

[0032] Example 2:

[0033] Weigh 5g methoxyfenozide, 50g spinosyn, 3g phenethylphenol polyoxyethylene ether phosphate, and agricultural milk 33 # 2g, Nongru 600# 1g, solvent oil 13g, add water to 100g. The above raw materials are put into the mixing kettle for high-speed mixing according to the conventional method of preparing the water emulsion to form the methoxenozide·spinosyn water emulsion with the main active ingredient weight percentage of 55%.

Example Embodiment

[0034] Example 3:

[0035] Weigh 2g methoxyfenozide, 18g spinosyn, 6g calcium dodecylbenzenesulfonate, 3g phenethylphenol polyoxyethylene ether phosphate, and agricultural milk 33 # 2g, Nongru 600# 1g, 10g cyclohexanone, add water to 100g. The above raw materials are put into a mixing kettle according to the conventional method for preparing microemulsions and mixed to form a methoxenozide·spinosad microemulsion with a main active ingredient weight percentage of 20%.

[0036] The efficacy test for controlling vegetable diamondback moth was carried out in Example 3. According to the dosage in Table 3, the dosage was 20g and 30g per mu. The control agent was 40% spinosyn EC (emulsifiable concentrate) 30g / mu and 15% beetle Hydrazide EC 30g / mu, with clear water as a blank control, check the results of 3 days, 7 days, 14 days and 28 days after the medicine. The treatment results are shown in Table 3:

[0037] Table 3: Field test results of methoxenic hydrazide and spinosyn paired vegeta...

Abstract

The invention discloses a composite insecticidal composition containing methoxyfenozide and spinosad and an application thereof. The insecticidal composition takes methoxyfenozide and spinosad as main active ingredients, wherein the weight ratio of methoxyfenozide to spinosad is (0.1-80):(0.5-80). The insecticidal composition can generate relatively high synergistic effect, overcomes and delays the drug resistance of insects, and realizes high insecticidal speed and long duration while the application cost is reduced and the prevention effect is obviously better than that of using a single agent. The insecticidal composition disclosed by the invention can prevent homoptera, lepidoptera, hemiptera, coleoptera, hymenoptera, orthoptera, diptera, thysanoptera and mite insects on crops and particularly realizes a special effect on the insects such as homoptera rice planthopper and aphid, lepidoptera plutella xylostella, cotton bollworm and beet armyworm, thysanoptera thrips and mites and the like, and the effect is obviously better than that of using a single agent.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a compound insecticidal composition containing methoxyfenozide and spinosyn and its application. Background technique [0002] Methoxyfenozide, chemical name: N-tert-butyl-N'-(3-methoxy-2-methylbenzoyl)-3,5-dimethylbenzoylhydrazide. The structural formula is: [0003] [0004] The pure product is a white powder with a melting point of 202-205°C. Water solubility at 20°C <1mg / L. Solubility in other solvents: dimethyl sulfoxide 11g / L, cyclohexanone 9.9g / L, acetone 9g / L. Stable in storage at 25°C, hydrolyzed at 25°C, PH=5, 7, 9. [0005] The methoxyfenozide preparation has low toxicity, the acute oral LD50 of rats is 5000mg / kg, and the acute percutaneous LD50>2000mg / kg. [0006] Methoxyfenozide is a kind of insect growth regulator, which mainly interferes with the normal growth and development of insects, even if the insects molt and die, and can inhibit feeding. ...
