[0017] Example : Indoor Activity Test for Floralaner Compounding

[0018] 1. Test reagents: 98% Floranad, 90% Tetrazolium, 97.6% Methifenazide, 90% Clothianidin, 95% Acethopronil, The above agents were obtained from the laboratory of the Institute of Biotechnology, Academy of Agricultural Sciences, Guangxi Zhuang Autonomous Region.

[0019] 2. Test object: Spodoptera litura collected from the taro planting area in Lipu City, Guangxi, and continuously reared for multiple generations with fresh taro leaves in the laboratory. Feeding conditions: temperature is 25±1℃, humidity is 60-80% , the photoperiod is L:D=(16:8)h, and the healthy 3rd instar larvae with the same size are selected as the test objects.

[0020] 3. Test method (refer to "NT / T 1154.14-2008 Pesticide Indoor Bioassay Test Guidelines for Pesticide Part 14: Leaf Soaking Method")

[0021] The test agent is first dissolved in dimethyl sulfoxide, and then diluted with 0.1% Tween-80 aqueous solution to prepare a singl...

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to an insecticidal composition for preventing and treating prodenia litura in a taro field. The invention relates to an insecticidal composition for preventing and treating prodenia litura in a taro field. The effective component of the insecticidal composition is prepared by compounding fluralab, tetratolfenpyrad, methoxyfenozide, clothianidin amide or acetoprole. When the fluralan is compounded with the tetratolfenpyrad, the methoxyfenozide, the clothianidin or the acetoprole, the co-toxicity coefficient in a certain mass ratio range is greater than 120, and a synergistic effect is shown. Therefore, the compound formula provided by the invention can improve the control effect on prodenia litura, and is beneficial to reducing the application dosage of pesticides, thereby greatly delaying the generation speed of drug properties of diseases and insect pests; meanwhile, pesticide residues and environmental pollution can be reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition for controlling Spodoptera litura. Background technique [0002] Taro is a perennial herb, and its bulbs are rich in various nutrients such as starch, vitamins and amino acids, and are widely cultivated vegetables and food crops around the world. At present, Guangxi has become one of the main producing areas of taro in the country. [0003] Spodoptera litura Fabricius is one of the main pests and diseases that harm the normal growth of taro. Spodoptera litura, belonging to the Lepidoptera Noctuidae, is a worldwide agricultural pest with the characteristics of wide distribution, multiple host species and serious economic harm. The pest damages in clusters of newly hatched larvae. After the 2nd instar, it gradually feeds on mesophyll, and after the 4th instar, it enters the overeating period. The 5th-6th instar larvae account for about 9...
