Problems solved by technology

Thrips use adults and nymphs to suck the juice of young plant tissues (twigs, leaves, flowers, fruits, etc.), the damaged young leaves and shoots become hard, curl and wither, the plants grow slowly, and the internodes shorten; young fruits (such as Eggplant, cucumber, watermelon, etc.) will harden after being killed, and cause fruit drop in severe cases, seriously affecting yield and quality

Embodiment Construction

[0015] Specific embodiments of the present invention are given below to further describe the composition of the present invention.

[0016] 1. Indoor bioassay experiment

[0017] 1.1 Test method

[0018] 1.1.1 Drug preparation

[0019] 95% horseradish crude oil (Allyl isothiocyanate), provided by Wuhan Green Century Bioengineering Co., Ltd. Soluble in 99.95% methanol and make 10000mg / L mother liquor for later use. 95% nicotine water agent, provided by Xi'an Runze Biotechnology Co., Ltd. Add water to make 10000mg / L mother liquor for later use. Each compound ratio of horseradish and nicotine is diluted into 5-7 concentration gradients.

[0020] 1.1.2 Film production

[0021] Prepare a 9cm-diameter petri dish, take a 9cm-diameter qualitative filter paper and put it on the bottom of the dish, absorb 1ml of the prepared medicine solution and evenly drop it on the filter paper, make a medicine film after the solvent evaporates, and place it for 24 hours before use.

Abstract

The invention relates to a botanical insecticide and in particular relates to an allyl isothiocyanate and nicotine compound insecticide and application thereof. The active ingredients of the compound insecticide are allyl isothiocyanate and nicotine, wherein the weight ratio of allyl isothiocyanate to nicotine is (2:1)-(1:4), the preferable ratio is (1:1)-(1:3) and the optimal ratio is 1:3. Allyl isothiocyanate and nicotine show obvious synergism when being applied to controlling thrips on strawberries after being compounded. The compound insecticide shows outstanding effect on controlling thrips on strawberries.

Description

technical field [0001] The invention relates to a botanical insecticide, in particular to a compound insecticide of horseradish and nicotine and its application. Background technique [0002] For a long time, due to the extensive use of chemical pesticides in production to ensure the output and quality of agricultural products, there has been a huge pressure on the ecological environment, and some pests have rapidly developed resistance to pesticides, further increasing the amount of pesticides, resulting in the occurrence of pesticides in agricultural products. The residual amount seriously exceeds the standard, causing great harm to humans, animals and the environment. The development and utilization of environmentally compatible and harmless pesticide resources are increasingly favored by various countries. [0003] Botanical pesticides are a class of pesticides made from plants or plant extracts. Like microbial pesticides, they are biological pesticides. Their active in...
