Sugarcane disease-and-insect-pest control method

Abstract

The invention discloses a sugarcane disease-and-insect-pest control method. The method includes the following steps that during the sugarcane seedling stage, urea, detergents and clean water are added in trapping basins with the diameter ranging from 20 cm to 30 cm according to the proportion of 1:1.5:110 and are mixed and stirred evenly, and lure cores are fixed to the positions 1 cm to 3 cm away from the water surfaces of the trapping basins; the trapping basins are evenly placed in a sugarcane cultivating field at 100 cm to 150 cm intervals, and 2 to 4 trapping basins are arranged per mu; after the sugarcane seedling stage, artificial host egg cards are evenly inserted on sugarcane leaves at 2 m to 3 m intervals, and the artificial host egg cards are replaced once every 15 days to 20 days; trichogrammas are released, wherein 10,000 to 20,000 trichogrammas are released pre mu every time, seventy five to one hundred and twenty releasing points are arranged per mu, and trichogramma releasing is conducted five to seven times all year. The sugarcane disease- and-insect-pest control method is easy to operate and environmentally friendly, the trichogrammas are adopted to control insect pests such as moths, the remarkable effect is achieved, the diseases and insect pests can be controlled effectively, the safe saccharose industry is guaranteed, the usage amount of the chemical pesticides in the sugarcane disease-and-insect-pest control process can be controlled beneficially, the risk that pesticide residues exceed the index in agricultural products is lowered, and the agricultural non-point source pollution is controlled.

Description

technical field [0001] The invention relates to a method for preventing and controlling sugarcane diseases and insect pests. Background technique [0002] With the development of our country's economy, people's living standards have also been greatly improved, and people's attention to pollution-free food is also more intense, which requires the sugarcane industry to develop pollution-free production. Sugarcane is a crop with a long growth cycle and continuous planting. In recent years, with the development of sugarcane production, changes in agricultural farming systems, frequent introductions, abuse of chemical pesticides, and changing environments, new changes have taken place in the dynamic relationship between crops and pests, pests and natural enemies. The emergence of drug resistance and the continuous reduction of natural enemy populations have weakened the effect of restraining the natural factors of pests, greatly reduced the yield of sugarcane, increased the prod...

Problems solved by technology

In recent years, with the development of sugarcane production, changes in agricultural farming systems, frequent introductions, abuse of chemical pesticides, and changing environments, new changes have taken place in the dynamic relationship between crops and pests, pests and natural enemies. Drug resistance, natural enemy populations continue to decrease, weakening the role of natural factors to restrain pests, greatly reducing the yield of sugarcane, increasing the production cost of sugarcane, and seriously affecting the industrial development of sugarcane

At the same time, the abuse of pesticides not only fails to prevent and control sugarcane pests and diseases, but also causes pesticide residues, pollutes the environment, endangers human health, and poses a threat to environmental safety.
