Embodiment 1

[0023] Weigh 30 g of diafenthiuron 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 diafenthiuron·spinosad emulsifiable concentrate with a main active ingredient of 30% by weight. The specific ratios of diafenthiuron 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 res...

Embodiment 2

[0034] Weigh 5g of diafenthiuron, 50g of spinosad, 3g of tristyrylphenol polyoxyethylene ether phosphate, 2g of agricultural milk 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 emulsion, and mix at high speed to form a diafenthiuron·spinosad water emulsion with a main active ingredient weight percentage of 55%.

Embodiment 3

[0036] Weigh 2g of diafenthiuron, 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 diafenthiuron·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 g / liter spinosad SC and 50% diafenthiuron WP, dilute according to the dilution multiple in table 3, check 3 days after medicine, 7 Day, the result of 14 days, the processing result is shown in Table 3:

[0038] Table 3: Field test results of diafenthiuron-spinosyn compound against resistant cotton bollworm

[0039]

[0040] Field drug efficacy results show that diafenthiuron·spinosyn composition has excellent control effect on resistant c...

Abstract

A composite pesticidal composition comprising diafenthiuron and spinetoram and uses thereof are disclosed. The composition adopts the diafenthiuron and the spinetoram as pesticidal active components, wherein the weight ratio of the diafenthiuron 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 a compound insecticidal composition containing diafenthiuron and spinosad and its application. Background technique [0002] Spinetoram, the structural formula is: [0003] [0004] XDE-175-J is a new type of spinosad insecticide produced by Dow AgroSciences, and received the first global registration, mainly used to control Lepidoptera larvae, thrips and leaf miners, etc. , It has a good control effect on diamondback moth, beet armyworm, leafminer, thrips, armyworm, pod borer. [0005] Diafenthiuron, chemical name: 1-tert-butyl-3-(2,6-diisopropyl-4-phenoxyphenyl)thiourea. Structural formula: [0006] [0007] Diafenthiuron is a new type of thiourea high-efficiency insecticide and acaricide, which has contact killing, stomach poisoning, systemic and fumigation effects, and has a certain ovicidal effect. It is transfo...
