Flowers conduct biological safety

Biological control is to reduce drug use, avoid flowers produce a measure of resistance .

One can make use of pest disease, lethal bacteria, fungi , viruses or their metabolites to control pests . Usually cultured microbial virulence of the pest , and then made ​​into powder spraying , so that pests death. Such as bacteria Bacillus thuringiensis preparations against lepidopteran insect larvae highly toxic , killing excellent results. Experimental results show that the effect is also very good fungal pest . Such as the use bassiana parasites in the Lepidoptera, Coleoptera and other insects and worm class body , can be very effective in killing pests. Poplar lice red seat molds for whitefly has a high virulence . The use of research and application of pest control virus also made ​​great progress in the application of more nuclear polyhedrosis virus . Strong expertise insect virus resistance , garden pressure sprayer virulence is also strong, lasting effect. Practical applications often made ​​of the virus preparations agent, platinum , wettable powder , etc. applied into the soil or spraying pest control .

Second, the use of microbial antagonism between and certain microbial metabolic products , to inhibit the growth of pathogenic microorganisms flowers , development, and even to death. Such material is antibiotics. If code is " 5406 " flower flower fertilizer can prevent certain fungal diseases , bacterial diseases and mosaic virus .

Third is to use the nature of the food chain , food chain relationships or parasitic relationship to combat pests. For example, the use of daylight bee control aphid ; bottle sprayer utilization dragonflies, praying mantis and other predatory insects and so on.

But also the use of plant immunity and Vegetable saps the active ingredients to combat pests and diseases. As with aqueous garlic can prevent many types of bacteria. Physiologically active substances to the use of plant pest is currently the focus of research at home and abroad , is one of the ways a good prospect . In addition the use of biological pest control engineering approach is also a new trend of development, such as genetically modified technology.
