pesticides

The use of pesticides to control crop pests, in order to achieve the best killing effect, in addition to selecting the right counterpart of the pharmaceutical, timely use of drugs, but also pay special attention to the use of time and parts of the drug.

First, according to the characteristics of the climate and pest day and night activity patterns, choose to apply the drug at a favorable time.

Application of pesticides time to 9 ~ 10 am and 4 pm or later is preferred. Because after 9 a.m., the dew on the crop leaves has dried up, and it is the time when the sunrise pest activity is at its peak.

In this time to apply the drug, not only because the dew will not dilute the liquid affect the control effect, but also can make the pest and pesticide direct contact, increase the chance of pest poisoning.

After 4 p.m., the sun is in the west, the light is weakened, the temperature is reduced, and it is the dusk flying activities and nighttime pests are about to come out of the time, the application of drugs at this time, can be applied to the crops in advance of the agent.

To be pests in the dusk and night out of the activities or feeding on its contact with the venom or feeding poisoning death, but also to avoid the loss of evaporation and photolysis of the liquid failure.

Second, according to the harmful parts of the pests, choose different pharmaceuticals and take different methods of application, delivery of drugs in place.

For example, if the pests harming the roots, the medicine will be applied to the roots or applied in the sowing ditch; on the back of the leaves to feed on the pests will be sprayed on the reverse side of the leaves.

For the control of red bollworm and cotton bollworm, the medicine is applied to flower buds, green bollworms and tips of clusters;RAMBO insect killer supplier for the control of stem borers that cause withered seedlings, the poisonous soil is sprinkled; for the control of white ears, the medicine is sprayed or doused.

Preventing and controlling rice fly, rice leafhopper will be sprayed to the base of the rice plant; preventing and controlling the oblique pattern night moth will be sprayed to the flower buds and young pods.

In addition, the cotton aphid, red spider, rice fly, rice sharpshooter and other hidden pests, according to its piercing sucking mouthparts feeding mode, can choose the strong absorption of insecticides absorbed by other parts of the plant to achieve the purpose of the delivery of the drug in place.

Only because of the insect application, delivery of drugs in place, in order to hit the key points, to achieve the effectiveness of the drug to the insect removed, so that the drug to play the best role, to obtain the desired effect of killing insects.

Insecticides why the more you use the more ineffective!

A pharmaceutical, the beginning of the use of insecticidal effect is often very good, but with the dosage continues to increase and the use of the expanding range of cases of rising drug resistance continue to appear.

The most prominent is cis-cypermethrin, that is, in the 80's advertisements are often said to be the "righteousness of the rifling", soon can not do justice, because even if you increase the dosage of dozens of times or even hundreds of times the amount of drugs or drug concentration can not kill the pests.

This is actually due to the development of drug resistance, that is, the ability of pests to tolerate the amount of drug that kills most of the individuals in a normal population and to develop in their own populations.

In fact, pest populations in nature already have individuals with different levels of sensitivity to pesticides. The process of using pesticides is actually a process of selection of insect populations by the pesticide.

Each use of pesticides, will leave relatively resistant individuals, kill the relatively sensitive individuals, but also make the level of pest resistance more or less increased.

Current status:

(1) The emergence of drug resistance is related to the pests and their life habits. Short life history, the number of breeding generations per year, more exposure to pharmaceutical pests, such as mites, shellfish, aphids, mosquitoes, etc. are most likely to produce resistant populations.

(2) A pest resistant to a pesticide, often the same type of other pesticides are also resistant; different insecticidal mechanism of the drug is not easy to occur between such interactions; (3) the same pesticide, the same insecticidal mechanism of the drug is not easy to occur; the same insecticidal mechanism of the drug is not easy to occur.

(3) the same kind of pesticide continuous use of a number of times or high concentration of treatment, the formation of resistance fast, and vice versa is slower.

Knowing this, we can prevent or delay the rise of pest resistance through rational use of drugs.

In order to advocate the use of integrated control, including the selection of breeding, promotion of resistant varieties, improved cultivation techniques, the development of biological, physical and other technologies to minimize the number of times and the amount of pharmaceutical control.

The second is to choose insecticides with different mechanisms of action mixed, rotating and mosaic application.

Third, improve the application techniques,VITFE insect killer manufacturer such as symptomatic use of drugs, timely spraying, the choice of high-efficiency equipment, spraying in place, etc., as much as possible to improve the killing effect.

Attention to the purchase of pesticides

Like other commodities, pesticide commodities also have many problems, consumers should pay attention when buying. In addition, pesticides are a special commodity, which involves a lot of knowledge and technology, consumers should be more careful when purchasing.

Do not buy pesticides that do not have an active ingredient labeled.

Among chemical pesticides, pyrethroids are recognized as safer than organochlorines, organophosphates and carbamates. Among the many pyrethroid insecticides, safety varies, with Permethrin, Permethrin, Permethrin and Deltamethrin generally being safer.

Don't buy insecticidal products made with insecticides that have been banned for use.

Aerosol insecticides and other products should strictly implement the "three certificates" system of labeling the license number, pesticide registration number and product quality standard number, otherwise they are illegal commodities and should not be purchased.

Foreign pesticide commodities entering the domestic market should also be carefully identified, not blindly trust.

Precautions for use

Use pesticides sparingly, and try not to use them when they can be used. Minimize contact with pesticides, such as do not stay in the room where the pesticide is applied, you should leave immediately after applying the pesticide,Chinese SLEEP COOL Insecticide spray and open the door and windows after one and a half hours to fully ventilate the room before entering.

Do not expose infants and children with underdeveloped brains to pesticides to avoid adverse effects on the development of the child's brain.

Take extra care when using pesticides in the kitchen and do not allow them to contaminate food, kitchen utensils, etc.

Shower and change clothes after applying insecticides and insecticidal creams.
