Embodiment 1

[0023] Weigh 30 g of metaflumizone 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 of preparing EC and mix them to prepare Metaflumizone·Spinocid EC with a main active ingredient of 30% by weight. The specific ratios of metaflumizone 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 the results are shown in Table 1:

Embodiment 2

[0034] Weigh 5g of metaflumizone, 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. The above raw materials are put into a mixing tank according to the conventional method for preparing water-based emulsions and mixed at high speed to form a metaflumizone·spinosad water-based emulsion with a main active ingredient of 55% by weight.

Embodiment 3

[0036] Weigh 2g of metaflumizone, 18g of spinosad, 6g of calcium dodecylbenzenesulfonate, 3g of tristyrylphenol polyoxyethylene ether phosphate, 2g of agricultural milk 33#, 1g of 600#, cyclohexane Ketone 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 metaflumizone·spinocid microemulsion with a main active ingredient of 20% by weight.

[0037] Carry out control cotton bollworm efficacy test to embodiment 3, contrast agent is 60 grams per liter of spinosad SC and 25% metaflumizone SC, dilute according to the dilution factor in table 3, check 3 days after the medicine, The results of 7 days and 14 days, the processing results are shown in Table 3:

[0038] Table 3: Field test results of metaflumizone-ethyl spinosad compound resistant cotton bollworm

[0039]

[0040] The results of field efficacy showed that the combination of metaflumizone·ethyl spinosad had exc...

Abstract

A composite pesticidal composition comprising metaflumizone and spinetoram and uses thereof are disclosed. The composition adopts the metaflumizone and the spinetoram as pesticidal active components, wherein the weight ratio of the metaflumizone to the spinetoram being 0.1-80:0.5-80. The composition can generate a high synergistic interaction, overcomes and delays pest resistance to pesticides, is high in pest killing speed, long in duration of efficacy, and reduced in pesticide using cost, and has control effects obviously higher than effects when a single pesticide is used. The composition can control lepidoptera pests on crops, especially can control cotton bollworm and stem borers, and has effects obviously higher than the effects when a single pesticide is used.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides containing heterocyclic compounds, and in particular relates to an insecticidal composition containing metaflumizone and spinetoram and application thereof. Background technique [0002] Metaflumizone, chemical name: (E+Z)-2-[2-(4-cyanobenzene)-1-(3-trifluoromethylbenzene)ethylidene]-N-( 4-trifluoromethoxyphenyl) hydrazine oxamide. The structural formula is: [0003] [0004] Metaflumizone (BAS320I) is a brand-new compound jointly developed by German BASF and Japanese pesticide company, which belongs to semicarbazone insecticides. Metaflumizone has a unique mechanism of action, has insecticidal activity itself, does not require biological activation, and has no cross-resistance with existing various insecticides. Metaflumizone can effectively control Lepidoptera pests and some Coleoptera larvae and adults in various places, and can also be used to control ants, termites, flies, cicad...
