Abstract

The present invention relates to a method for protecting plants or plant protection material against attack or infestation by insects, fungi, arachnids, nematodes and harmful weeds by treating roots / buds / seeds / soil with active compounds in combination with enzymes.

Description

Technical field [0001] The present invention relates to a method for protecting plants or plant protection materials against attack or infestation by insects, fungi, arachnids, nematodes and harmful weeds by treating roots / shoots / seeds / soil using active compounds in combination with enzymes. dyeing method. Background technique [0002] Agricultural chemicals, including insecticides, fungicides, herbicides, miticides (or acaricides), and plant growth regulators, are available as emulsions, wettable powders, granules, dusts, and Used in mobile and other forms. Various attempts have been made on the properties of these agrochemical formulations to achieve maximum efficacy of the agrochemicals. However, it is difficult to enhance the efficacy of agricultural chemicals by adjusting their formulations. Developing new agricultural chemicals is even more difficult. Therefore, further enhancing the efficacy of existing agrochemicals will contribute significantly to the industry. ...
