Embodiment Construction

[0094] Combined toxicity of spirotetramat and indoxacarb in different ratios

[0095] 1.1 Drugs to be tested

[0096] 95% spirotetramat technical, 67% indoxacarb technical, spirotetramat and indoxacarb mixture in different proportions.

[0097] 1.2 Sources of indoor test insects

[0098] Rice leaf rollers were collected from the field, and were reared indoors with rice seedlings until the third instar for testing. Indoor conditions: temperature (25±2)℃. The relative humidity is 65%±5%, and the photoperiod is 12 / 12h (L / D).

[0099] 1.3 single dose determination method

[0100] Using the rice stem dipping method, dig out robust and consistent rice plants at the mid-booting stage, wash them, cut them into 15cm-long connected rice stems, and dry them in a cool place until there is no water mark on the surface, and set aside. According to the results of the preliminary experiment, the original drug was dissolved with a small amount of acetone, and then diluted to 5 different c...

Abstract

The invention discloses a pesticidal composition containing spirotetramat and indoxacarb, and a preparation method and application thereof. The pesticidal composition is characterized by containing spirotetramat, indoxacarb and other auxiliaries, wherein the weight ratio of the spirotetramat to the indoxacarb is (0.1-70):(0.1-80). The pesticidal composition can be used for preventing and controlling multiple pests of multiple crops. The composition is safe and environment-friendly, and has low cost and a good effect. The indoor toxicity test and field pesticide effectiveness test prove that the complexing of the two compounds has an obvious synergic effect on the target pest. As the mixing of spirotetramat and indoxacarb has not been reported home and abroad, the pesticidal composition is proposed.

Description

technical field [0001] The invention belongs to the field of pesticide compounding, and relates to an insecticidal composition and its application, in particular to an insecticidal composition with spirotetramat and indoxacarb as main active ingredients and its application. technical background [0002] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the generation of pest resistance. Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution. Reasonable compounding or compounding of chemical insecticides can expand insecticidal spectrum, improve control effect, prolong application period, reduce dosage, reduce phytotoxicity, reduce residue, and delay the occurrence of drug resistanc...
