Definitions

  • the present invention relates to a pesticidal composition comprising flufenicol and fenthrin; in particular to a method of controlling pests.
  • the main method for the prevention and control of pests that are resistant to agriculture is to develop a new component that has no cross-resistance with existing varieties or a compound between existing pesticides.
  • the former has high development cost and long cycle.
  • the current development speed is far less than the speed of pest resistance. Therefore, it is an optimal choice for the mixing of existing pesticides with different mechanisms of action. If the ratio is reasonable, it can produce significant synergistic effects, making the field control effect significantly better than the effects of each single agent.
  • Insecticides containing a single active ingredient often have certain defects in the control of agricultural pests. Continuous use for many times not only makes the pests susceptible to drug resistance, but also easily causes pollution to food and the environment, and is reasonable between the active ingredients of the pesticide.
  • Compounding can overcome the above disadvantages.
  • rational compounding can increase the synergistic effect of the active ingredients, improve the control effect, reduce the amount of active ingredients, save costs, delay the production of insecticide resistance, and can reduce or even avoid the pollution of food and environment by pesticides.
  • the low-toxic and high-efficiency new pesticide developed by the invention not only has a significant effect on the target, but also has a low impact on humans, crops, non-targets and the environment.
  • Flumazepam is developed by the Japanese Pesticide Company and belongs to a class of new quinazoline (m-diazabenzene) insecticides. Flumazepam is generally applied as a water-dispersible granule. Its mechanism of action is to stop the pests from feeding and starvation, thereby preventing plant tissues from suffering more damage and limiting the spread of some important diseases. At present, it is mainly used to control whiteflies, mites and scale insects on vegetables, fruit trees and tea leaves.
