Problems solved by technology

[0002] At present, the insecticidal and disease-resistant products commonly used in the market are mainly chemical pesticides. These products have remarkable effects in insecticidal and weed control, but the harm to the environment of chemical pesticides during use, the residues of chemical pesticides and Nondegradability affects people as well as plants themselves
Green pesticides are an innovation of chemical pesticides. At present, there are some green pesticides on the market, which can prevent a variety of diseases and insect pests, can effectively fight bacteria, prevent diseases and insect pests, and do not pollute the environment after use. However, most of these products are difficult to degrade after use.

preparation example Construction

[0031] The preparation method of the humic acid type green environmental protection antibacterial anti-insect pheromone medicament comprises the following steps:

[0032] 1) Weigh the weathered coal sample after 120 mesh drying, add dilute hydrochloric acid at a ratio of 1g:(10-25) mL of solid-liquid ratio, heat and boil to activate, wash the precipitate to neutral after cooling, and then press 1:(8 The solid-to-liquid ratio of ~10) was added with 10% ~ 20% sodium hydroxide solution, heated and stirred in a boiling water bath at 100°C for 1 ~ 3 hours, cooled to room temperature, centrifugally filtered, and weighed the quality of the impurities after alkali dissolution; Add dilute hydrochloric acid to the filtrate to adjust the pH to 1-3, let it stand for 24 hours, filter it, collect the precipitate and dry it to constant weight to obtain humic acid.

[0033] 2) Weigh 1 g of humic acid and dissolve it in 10 mL (20%) of a strong alkali with a pH of 11 to 14 to obtain a humate so...

Abstract

The invention provides a humic acid type antibacterial insect-proof pheromone agent, and a preparation method and a use method thereof. The humic acid type antibacterial insect-proof pheromone agent comprises, by mass, an agent A and an agent B, the agent A comprises, by mass, 10 parts of humic acid, 2-6 parts of alginic acid, 1-4 parts of natural antibacterial substances and 4-6 parts of natural insect prevention pheromone; ad the agent B comprises, by mass, 3-5 parts of calcium chloride, 1-2 parts of magnesium sulfate, 0.05-0.1 part of zinc sulfate and 500 parts of water. During use, the agent A and the agent B are applied to crops in sequence according to the volume ratio of 1: 1. The agent A and the agent B are sequentially applied, and the agent B and the agent A are crosslinked to quickly form a polymeric membrane to prevent attack of diseases and pests; meanwhile, humic acid in the agent A, natural antibacterial substances and natural insect-proof pheromones synergistically play an antibacterial role, so that the insect-proof and antibacterial properties and the like of the membrane are improved. The agent provided by the invention is biodegradable.
