Embodiment 1

[0025] Weigh 10 g of spinosad, 5 g of lufenuron, 10 g of sodium lignosulfonate, 14 g of ethylene glycol, 0.5 g of xanthan gum, 3 g of stabilizer, 0.5 g of antifoaming agent silicone oil, and water to a total weight of 100 g. After mixing evenly, ball mill in a ball mill for 2 to 3 hours, so that the particle size is all below 5 μm to form a 15% lufenuron·spinosad suspension concentrate.

[0026] Indoor synergistic bioassay was carried out, the resistant diamondback moth was selected as the target pest, each treatment was repeated 3 times, and 60 heads were treated at each concentration, and the co-toxicity coefficient was calculated according to the Sun Yunpei method with the LC50 value:

[0027] Table 1. Indoor determination results of 15% spinosad lufenuron suspension concentrate and its single dose against resistant diamondback moth:

Embodiment 2

[0033] Weigh 20g spinosad, 10g lufenuron, 3g phenylethylphenol polyoxyethylene ether phosphate, agricultural milk 33 # 2g, 1g of alkylphenol polyoxyethylene ether, 13g of xylene, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing water-based emulsion, and mix to form a 30% spinosyn-lufenuron water-based emulsion of water-emulsion preparation.

Embodiment 3

[0035] Weigh 40g spinosad, 5g lufenuron, 5g sodium dodecylbenzenesulfonate, 4g phenethylphenol polyoxyethylene ether phosphoester, polyoxyethylene polyoxypropylene diluted block compound such as Nongru 33 # 2g, 2g of alkylphenol polyoxyethylene ether, 13g of cyclohexanone, add water to make the total weight 100g. The above raw materials are put into mixing according to the conventional method for preparing microemulsions to form a 45% spinosad·lufenuron microemulsion microemulsion.

[0036] Carry out drug effect test result to embodiment as follows:

[0037]

[0038]

[0039] Note: a means significant at a=0.05 level, b means there is a difference at a=0.05 level, c means not significant at a=0.05 level;

[0040] Field drug efficacy results showed that the combination of spinosad and lufenuron had excellent control effects on resistant diamondback moth, and the control effects were better than those of single-dose varieties and better than the effects of each single pro...

Abstract

The invention relates to a desinsection composite and the application thereof, and is characterized by particularly relating to a desinsection composition taking spinosad and lufenuron as the main active components and the application thereof. The desinsection composite formed by two effective components which are the spinosad and the lufenuron respectively and an additive and an excipient, and all the components can be prepared into an emulsifiable concentration, an aqueous emulsion, a microemulsion and a suspending agent, wherein the weight percentage of the spinosad and the lufenuron is 0.5-60: 1-40. The desinsection composite has the advantages of generating higher synergy, overcoming and deferring drug resistance of pests, enlarging a control spectrum, having quick acaricidal effect, reducing medication cost and lightening toxicity and the pollution to the environment, thus being suitable for controlling high-resistance diamond back moths and asparagus caterpillars. The effect of the composite is obviously higher than the relative single-dose use.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, which is characterized in that it is an insecticidal composition with spinosad and lufenuron as main active ingredients and its application. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, higher and higher requirements are put forward for the quantity, quality and safety of agricultural products. However, in the past ten years, due to the high quality, high yield and diversification of rice, vegetables and other crops, as well as climate warming and the invasion of foreign pests, the occurrence of crop diseases and insect pests has generally increased significantly. Major pests such as rice leaf roller, rice borer, vegetable beet armyworm, Spodoptera litura, diamondback moth, and cabbage caterpillar frequently broke out. Among them, rice leaf roller and rice borer occurred in ...
