Problems solved by technology

However, safe and efficient biopesticides also have the disadvantages of slow efficacy and cost. Some biopesticides have a short residual effect period, some have a narrow insecticidal spectrum, and some are greatly affected by environmental factors, so they are difficult to be accepted by most farmers. , it is difficult to meet the needs of production
In addition, high cost is also a key factor restricting the development of biopesticide industry

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide composition of rotenone and cyfluthrin and its application as an insecticide. Background technique [0002] In recent years, people have paid more and more attention to the sustainable development of agricultural production and the coordination between human and the environment. The inherent limitations of chemical pesticides have become increasingly prominent. The research and development of a new generation of environmentally friendly pesticides has attracted much attention. The development of biological pesticides has been It has become an important trend to ensure human health and sustainable agricultural development. However, safe and efficient biopesticides also have the disadvantages of slow efficacy and cost. Some biopesticides have a short residual effect period, some have a narrow insecticidal spectrum, and some are greatly affected by environmental factors, so the...
