Problems solved by technology

Although there are also products in the market that use eugenol as active ingredients such as emulsions in water, suspension concentrates, and emulsifiable concentrates, these eugenol pesticides have used petroleum products such as aromatics, ketones, and straight-chain alkanes to varying degrees. Organic solvents not only have different degrees of environmental pollution, but also have low drug efficacy and high dosage of pesticides, resulting in high cost for farmers

Abstract

The invention discloses a eugenol biological pesticide which comprises the following ingredients in percentage by weight: 0.1% to 70% of eugenol, 6% to 20% of surfactant, 0.01% to 0.5% of plant immunity regulator, 10% to 50% of synergist, and raw materials of alcohol and turpentine for the rest part. With the advantage of reasonable formula, the eugenol biological pesticide is characterized in that the active volatility of the active ingredient eugenol is improved, the pesticide effect of the eugenol is enhanced, pesticide doses are reduced, and the pesticide cost for farmers is reduced; pureplant solvents are used in the eugenol biological pesticide which belongs to low-carbon and environment-friendly pesticide, so pollution and harm to the environment are reduced, and the eugenol biological pesticide is safe and environment friendly for use. The eugenol biological pesticide is used for preventing and treating powdery mildew, botrytis and downy mildew and regulating plant immunity, and has the effects of synergy, simultaneous treatment, resistance prevention, resistance delay, etc.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a biopesticide with eugenol as an active ingredient and a preparation method thereof. Background technique [0002] At present, the chemical agents used in large quantities in agriculture have brought great harm and many side effects to the protection of humans, livestock and the natural environment due to their toxic and side effects. Therefore, many developed countries have begun to work hard to develop and promote biological pesticides. Find ways to reduce the use of chemical pesticides. Eugenol is an extract of clove flower, which is a pure plant extract. Eugenol has anti-inflammatory, antipyretic and analgesic effects in medicine. Through experiments, it is found that eugenol has a strong effect of inhibiting or killing plant pathogenic fungi in plant protection. Compared with general chemical pesticides, it has the characteristics of good effect and low toxicity, and c...
