Bactericide for promoting growth and controlling rice sheath blight and application thereof

Abstract

The invention which discloses a bactericide for promoting the growth and controlling the rice sheath blight and an application thereof belongs to the field of pesticides for controlling crop diseases. The bactericide comprises 0.1-10 wt% of cinnaldehyde, 10-25 wt% of an emulsifier, 0.1-10 wt% of azone, 20-50 wt% of alcohol, and the balance water. The bactericide is used as follows: cinnaldehyde and azone are dissolved in alcohol and are uniformly mixed, and water is added to the obtained solution to a constant volume. The invention also discloses the application of the bactericide in controlling the rice sheath blight and promoting the rice growth. An effective component of the botanical bactericide of the invention is from a natural plant extract cinnaldehyde, and the bactericide of the invention has multiple efficacies of crop growth promotion, production and income increase, quality improvement, nutrient utilization rate improvement, pest control, no pollution and the like, so the bactericide of the invention is suitable for the production of nuisance-free, green and organic agricultural products. The bactericide of the invention, which has the advantages of low cost and substantial application effect, has a very wide application prospect.

Description

technical field [0001] The invention relates to the field of pesticides for crop disease control, in particular to a fungicide for promoting growth and preventing rice sheath blight and its application. Background technique [0002] Rice sheath blight, commonly known as "flower foot stem", "rotten foot blast", and "moire disease", belongs to tropical diseases and is one of the frequent and recurrent diseases of rice. In the middle of the 1990s, the survey results of the southern rice areas in my country showed that the incidence area of ​​rice sheath blight was 2.07 times that of rice blast, and the loss caused was 1.97 times that of rice blast, and its damage degree has far exceeded that of rice blast. , stripe leaf blight, etc., have become the number one disease of rice, posing a serious threat to high and stable rice yields. In recent years, due to abnormal climate, increased accumulation of soil bacteria, untimely control measures and extensive management of farmland, t...

Problems solved by technology

Jinggangmycin is the main drug for the control of rice sheath blight. The drug has systemic conductivity and has both preventive and therapeutic effects, but its duration is short. In recent years, when rice sheath blight has occurred seriously, The control effect of Jinggangmycin is even more difficult to guarantee

Moreover, with the use of chemical pesticides year by year, the resistance of sheath blight is gradually increasing. In order to achieve the desired effect, farmers increase the use of pesticides, which not only increases the amount of pesticide residues in crops, but also inhibits the growth of beneficial microorganisms in the soil. It will pollute the environment and increase production costs
