Downy mildew fungicide for promoting crop growth and application thereof

Abstract

The invention discloses a downy mildew fungicide for promoting crop growth and applications thereof, and belongs to the field of pesticides for crop disease control. The fungicide comprises, on a weight basis, 0.1-5% of cinnamaldehyde, 10-30% of emulsifiers, 0.1-10% of azone, 20-50% of alcohol, and the balance of water. During the preparation of the fungicide, cinnamaldehyde and azone are dissolved in alcohol respectively, and then are well mixed. The invention also discloses the applications of the fungicide in crop downy mildew control and crop growth promotion. The medical components of the botanical fungicide of the invention are derived from plant extract cinnamaldehyde which has insecticidal and fungicidal functions, and the fungicide has multiple efficacy of promoting crop growth and development, increasing production and income, improving quality, increasing nutrient utilization rate, controlling insects, causing no pollution, and the like, and is applicable to the production of pollution-free, green, and organic agricultural products. The preparation has significant application effect, easily available raw materials, simple production process, large market potential, obvious economic benefit and social benefit, and has extremely extensive application prospects.

Description

technical field [0001] The invention relates to the field of pesticides for crop disease control, in particular to a fungicide for downy mildew that can promote crop growth and its application. Background technique [0002] Downy mildew is a plant disease caused by downy mildew in fungi. It is a common harmful disease in cucumber cultivation and soybean cultivation. Cucumbers can develop diseases throughout the growth period, and the leaves of the plants can die within two weeks, resulting in a failure to harvest. The average rate of diseased plants is 40-90%, and the damage loss is generally 10-15%, or even more than 50%. Downy mildew has the characteristics of rapid spread, short incubation period, and ferocious onset. The light mildew will reduce the yield by 10-20%, and the severe one will reduce the yield by 30-50%. It directly affects the yield and quality of crops. become one of the main factors restricting the production of agricultural crops. [0003] At present...

Problems solved by technology

At present, there are also some botanical fungicides with cinnamaldehyde as the active component on the market, but the purpose is single, and the bactericidal effect often fails to achieve the expected purpose
