Daily Agricultural Economics
"Natural selection, survival of the fittest" This is the eternal survival criterion of nature, the directional selection of pesticides, so that some pests with drug resistance have been preserved, and with the enhancement of pest resistance, the amount of pesticides has been increasing, so the cycle has entered a vicious circle without an outcome, and the confrontation between spear and shield has become more and more intense. Many farmers are deeply touched that the pests are getting harder and harder to fight now!
There are many kinds of underground pests, mainly including caddisflies, grubs, golden needle worms, ground tigers, root maggots, root bugs, root aphids, quasi-ground beetles, crickets, root crickets, root leaf beetles, root celestial bulls, root elephant beetles and termites, which are distributed throughout China. The species of occurrence vary from place to place and are generally prevalent in dryland areas, especially grubs, grubs, goldenrods, ground tigers and root maggots.
What are the main reasons for the resistance of pests?
1, see the insect to prevent, ignore the prevention and control of the timing of medication
In general, young larvae are less resistant to pesticides and increase their resistance as they age. Therefore, the best period for pest control is the juvenile age before the third instar, before the insect volume is small and large quantities have not yet begun to feed in large quantities.
2. Increase the concentration or dosage of medication at will
Some farmers mistakenly believe that the greater the concentration of pesticides, the higher the effectiveness of the prevention of diseases and insects, and the pesticide preparation is not proportional, exceeding the specified concentration, which not only causes waste, but also is prone to drug damage, but also accelerates the resistance of diseases and insects.
3. Long-term use of single pesticide varieties
What can we do about drug resistance?
Rational use of medication
Scientific and rational use of drugs is undoubtedly a powerful measure to reduce drug resistance. It can be achieved by rotating drugs, mixing drugs, intermittent use or discontinuation of pesticides, adding synergists and diversified application methods, etc., the specific methods are not detailed, and there is a large amount of information.
Combined with physical and biological control
Physical control mainly includes high temperature shed disinfection, garden clearance, pruning, covering method (such as mulch film, insect net, etc.), yellow plate booby-trap, insecticidal lamp booby-trap, sugar water booby-trapping, trapping ball booby-trap, etc.
Biological control mainly includes insect control, fungus treatment, and the use of other beneficial animals to control pests. Through the combination of chemical control and physical control, pharmaceutical control and biological control, overall control, while achieving good prevention and control, to delay the emergence of drug resistance to the greatest extent.
Research and development of new drugs
It is inevitable that a drug will develop resistance after a long time, so it is very important to accelerate the research and development of new drugs. Although research and development work is done by professional people, what we need is to extend the time limit for the use of new drugs as much as possible.
