In order to achieve the best results, in addition to choosing the right chemicals and using them at the right time, special attention should be paid to the time and place of pesticide application.

First, according to the characteristics of different climate changes and pests of day and night to carry out activities to develop the law, choose to apply pesticides at a favorable time.

The best time to apply pesticides is 9-10 am and after 4 pm.RAMBO insect killer supplier Because after 9 am, the dew on the crop leaves has dried up, and it is the peak time for sunrise pest activities. Applied at this time, not only because the dew dilution will not affect the control effect, but also make the pests and pesticides direct contact, increasing the chance of pest poisoning. After 4:00 p.m., the sun goes down in the west, the light is weak, the temperature is low, the flight activities and nighttime pests are about to disappear at dusk, and applying pesticides at this time can be applied to the crop in advance. When pests come out at dusk and at night, they are exposed to the venom or die while feeding. At the same time, evaporation loss and photolysis failure can be avoided.

According to the harmful parts of the pests, choose different drugs, adopt different application methods and deliver the drugs in place.

For example, for social hazards as well as pests in the roots, these drugs will be irrigated and applied to the roots or applied to the sowing furrow; for pests feeding on the back of the leaves the problem will lead to the liquid directly sprayed on the reverse side of the plant leaves. To control red bollworm and cotton bollworm, the medicine is applied to a bud, green bolls and the tips of the cluster; to control stem borers that cause the formation of withered heart seedlings, the poisonous soil is sprinkled; to control white spikes, the medicine is sprayed or poured. Preventing and controlling rice fly and rice leafhopper will be carried out by spraying the liquid to the base of the rice plant; preventing and controlling angular oblique night moth will be no liquid sprayed to the flower buds and young pods. In addition, the cotton aphid, red spider, rice fly, rice leafhopper and other hidden main pests, according to its prickly sucking mouthpiece feeding mode, can choose the strong endosorption of insecticides can be absorbed after the plant has been passed on to other different parts of the plant, to achieve the purpose of the city to deliver the drug service to the right place. Only due to the insect application, delivery time in place, in order to effectively hit each other's vitals, to achieve the efficacy of the drug to the insect in addition to the effectiveness of the drug, so that the agent can play their best role, to obtain a kind of ideal insecticidal treatment effect.

Why use more insecticides the worse the effect?

When a pesticide is first used, the insecticidal effect is often very good, but with the increase in dosage and the expansion of the scope of application, cases of rising resistance continue to appear. Most notably, cis-cypermethrin, which was often advertised in the 1980s as the "lucky god of justice," soon failed to deliver justice because it could not kill pests even if the dose or concentration of the drug was increased dozens or even hundreds of times.VITFE insect killer manufacturer This is actually because the pests developed resistance, i.e., the ability to tolerate a dose that kills the majority of individuals in a normal population and develop it in their population. In fact, in natural pest populations, there are individuals with different sensitivities to pesticides. The use of pesticides is actually the process by which pesticides exert selection in insect populations. Each use of a pesticide leaves behind relatively resistant individuals, and the killing of relatively sensitive individuals more or less raises the level of resistance in the pest population.

It has been identified that:

(1) the occurrence of drug resistance is related to pests and their life habits. Pests with short life histories, many generations, and much exposure to insecticides, such as mites, mesquite, aphids, and mosquitoes, are the pests most likely to develop resistance

(2) A pest is resistant to a pesticide and often to other pesticides of the same type; such interactions are less likely to occur between drugs with different insecticidal mechanisms;

(3) The same pesticide is subjected to a high number of successive systemic applications or high treatment mass concentrations, and resistance develops quickly, and vice versa, more slowly. Knowing this, we teachers can can prevent or delay the rise of pest resistance through the scientific and rational use of drugs.Chinese SLEEP COOL Insecticide spray To this end, students are advocated to adopt an integrated control approach that mainly includes selecting and breeding, promoting resistant varieties, improving cultivation and management techniques, and carrying out a variety of biological, physical and other information technologies to minimize the number of times and the amount of drugs used in pharmaceutical control. The second is that the enterprise selects an insecticide with different impact action analysis mechanism in China to mix, rotate as well as mosaic application.

3. To improve the application technology, such as symptomatic use of drugs, timely spraying, the choice of efficient machinery, in situ spraying, etc., as much as possible to improve the effectiveness of insecticides.

The attention of the purchase of pesticides

As with other commodities, pesticide products also have many problems, consumers should pay attention to when buying. In addition to this, pesticides are a special commodity that involves a great deal of knowledge and technology, and consumers should be more careful when buying. Don't buy insecticides that are not labeled with active ingredients. Among chemical insecticides, pyrethroids are generally considered safe, while organochlorines, organophosphorus chemicals and carbamates are less safe. Many pyrethroids have varying safety profiles. Permethrin, permethrin, permethrin, permethrin and deltamethrin are generally safer. Do not purchase insecticide products that contain materials used in banned pesticides. Spray insecticides and other products should be strictly labeled with the standard production certificate number, pesticide registration certificate number and product quality standard number of the "three certificates" system, otherwise you can not buy illegal goods. Foreign insecticide commodities into our market should also be carefully identified, not blindly trust.

Precautions for use

Try to limit the use of pesticides, but do not use them when not in use. Minimize contact with insecticides. If you do not stay in the room where the pesticide is sprayed, leave immediately after spraying and open the doors and windows after one and a half hours to maintain air circulation. Do not expose infants and young children with underdeveloped brains to insecticides, as this may adversely affect children's brain development. Be more careful when using insecticides in the kitchen and do not allow them to contaminate food, kitchen utensils, etc. Bathe and change clothes after using insecticides and creams.
