In the process of farmers planting rice, it is inevitable to use pesticides to kill pests and diseases, but sometimes it is easy to encounter some misunderstandings of using pesticides, and the efficacy will naturally become worse. Then the next small series will tell everyone that the pesticides often encountered by farmers are misunderstood. You can see if you have any encounters.
Several misunderstandings of farmers using pesticides:
1, do not look at the instructions to dispense drugs
It is often the case that in order to rush to cure plant pests or diseases, or to be afraid of drugs, it is easy to increase the concentration of the drug during dispensing, so that plants are not only easy to produce drug resistance, but also highly susceptible to phytotoxicity. . In contrast, the random reduction of the dose does not achieve the control effect. Therefore, we can strictly follow the concentration ratio on the drug label when using the drug.
2, can not prescribe the right medicine
This is a common problem in production. Due to the lack of necessary plant protection knowledge, many farmers cannot diagnose correctly after the onset of symptoms, but blindly use drugs, thus delaying the timing of prevention. In view of the complexity of crop diseases, it is difficult to accurately determine the disease; and there are few professional plant protection personnel, so try to choose broad-spectrum sterilization products or combinations.
3, medication in advance
Because the disease has a certain incubation period, when the plant shows obvious symptoms, it indicates that the bacteria have invaded the plant for some time. Sometimes it is very effective to take medication in advance (just in time for the incubation period). Therefore, we advocate early prevention for diseases, but please grasp the time! It is necessary to grasp the occurrence period and regularity of various diseases, and prevent the spraying before the disease occurs, which may have the effect of getting twice the result with half the effort. If the time to fight drugs is too early, it still has no effect.
For pests, we do not recommend taking drugs in advance! Because most of the insecticides currently used in the market are contact agents or stomach poisons, only insects that come into contact with or swallow the drugs will play a role in killing insects. When you don't have worms, it's a waste of cost. Therefore, we advocate the use of drugs in the early stages of pests, because at this time pests are not highly resistant, and the feeding habits are not large. The insecticidal effects of pesticides can be fully exerted, and the degree of damage to plants will not be greatly affected.
4, the pursuit of quick-impact
If quick-acting is used when using insecticides, it is hoped that the pests will be killed immediately after spraying. However, some bio-pesticide insecticides are not easy to show effects because they only kill eggs or inhibit insect molting or slow effect, but are ignored by farmers. The most serious consequence of the quick-acting effect of farmers' friends is that the use of highly toxic, highly toxic and high-residue pesticides in some places still exists, and the pesticide residues in the products produced exceed the standard.
5, free to increase the concentration of drugs or the amount of medication
Pesticide configuration is not proportional, no special measuring tools, only bottle caps and other non-standard utensils; no quantitative concept, generally exceed the specified concentration, not only cause waste, but also prone to phytotoxicity, but also accelerate the resistance of pests and diseases .
6, the treatment is not difficult enough
Some pests and diseases can be removed from the disease, and once effective. Others need to be completely cured after several consecutive days of medication. For example, red spiders and aphids in insects often overlap in generations, that is, eggs, nymphs, and adults coexist, and most of the agents have no effect on eggs. Therefore, it is necessary to continuously apply the pesticide 2 times to 3 during the continuous incubation process of the pests and the effective period of the drugs. Times. The prevention and treatment of diseases generally requires three consecutive sprayings from 3 days to 5 days.
Ok, what I want to share with you today is this. Farmers’ friends should pay more attention to the use of pesticides. It is best not to enter the above misunderstandings. Otherwise, it will easily affect the efficacy. I hope this article can help Need friends!

Active Pharmaceutical Ingredients
Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
