How to use pyrethroid pesticides reasonably?

You can understand the specific effect of this pesticide, and also pay attention to the virus of the main ** of this pesticide, and then use it according to the instructions for use.

This kind of pesticide should be formulated according to the proportion, so that the pesticide can play the best effect, so that it can be used more reasonably, and it can also play a role.

It needs to be selected according to the actual situation, and it needs to be used in accordance with the scientific ratio, and it must be used cautiously according to the specific situation.

There is no such thing, only syringoxystrobin is a fungicide that has the effects of immune, prevention, increasing production and income. It is the most authoritative agent for the prevention and control of apple tree rot disease in the country. It has a wide bactericidal spectrum, and is effective for downy mildew, late blight, scab, anthracnose and leaf mildew of melons, vegetables, fruit trees; At the same time, it is also effective for ring pattern disease, anthracnose, cotton wilt, rice plague, blight, wheat root rot and corn small spot disease.

Pyrethrin is generally a fast-acting insecticide.

Does syringrobin work against bacteria?

When using, you must pay attention to the amount, and you must pay attention to the time of spraying, you must choose when the temperature is more suitable, you must not choose in rainy days or when the temperature is relatively high, and you must pay attention to dilution with water, and you can also use several pesticides at the same time.

In the process of use, we must pay attention to safety, avoid contact with **, wear protective clothing during use, be sure to choose a good time, avoid heavy rain or windy weather, and avoid volatilization.

First of all, we must pay attention to the principle of proportioning, when proportioning, we must stay away from water sources, we must wear protective clothing, protect our own **, we must use it immediately after the proportion, and we must put it in a cool and ventilated place when storing.

Permethrin has low toxicity to higher animals and is easy to decompose when exposed to sunlight. It can be used to control a variety of pests on cotton, vegetables, tea and fruit trees, especially suitable for the control of sanitary pests.

Amethhrin is used to control mosquitoes, flies, cockroaches and other health pests, has a useful and strong knockdown effect on contact killing, and has a repellent effect on cockroaches, and the lethal effect is still lacking. Mixed with other hygienic pesticides that are safe for humans and animals, all aerosols are used.

Extended Information: Precautions for using methrin:

Do not spray pesticides directly at people and pets. Avoid exposure of infants, children, pregnant women and people with specific allergies to pesticides to avoid adverse effects. Do not spray pesticides on food, utensils, furniture and bedding when using pesticides.

Keep pesticides safe and out of reach of small children.

Among the chemical insecticides, pyrethroid insecticides are generally considered to be safer, and permethrin, methrin, allethrin and deltamethrin are generally safer. Organochlorines, organophosphates, and carbamate are less safe.

In addition to having low residues and a certain control effect on pests, pyrethroid pesticides have a good control effect on mites and underground pests. The use of pyrethroid pesticides, due to the large use of pyrethroid pesticides, will cause a variety of pests to develop a certain resistance. Therefore, when pyrethroid pesticides are used, pyrethroid fever should be effectively prevented and the application should be strictly controlled.

dose and frequency; Repeated use of pyrethroid pesticides can develop some resistance to pests. According to the survey, pyrethroid pesticides can only be used 2-3 times during the growth period, and each time they are used according to the instructions. <>

When pyrethroid pesticides are used, other pesticides should be used alternately, which is more conducive to reducing the frequency of pyrethroid pesticides and preventing pests from developing resistance. After testing, it can be combined with insect poison insecticides and agricultural specials; with organophosphorus pesticides monocrotophos, phosphine, dimethoate, quinafs, hydrocarbon phosphorus; It is used in rotation with carbamate pesticides, leafhopper powder, methocarb and other pesticides. <

Pyrethroid insecticides are a broad-spectrum insecticide that controls a wide range of pests. Its insecticidal effect is comparable to that of traditional insecticides such as organophosphorus and organochlorine. 10 to 100 times more effective.

The principle of action of pyrethroid insecticides is to disrupt the normal physiological function of the nerves of pests, so that pests die due to abnormal excitement, convulsions, and paralysis. In addition, due to the small dosage and relatively low application concentration of this type of drug, it is relatively small to humans and animals, and the pollution to the environment and ecology is relatively small. The disadvantage of this type of agent is that it is very toxic to aquatic organisms such as fish, and it cannot be used correctly to select natural enemies, and there is no systemic absorption.

Pyrethroids are usually much more effective at killing pests than the insecticides we commonly use, and they are faster and have a stronger knockdown ability. Another point is that it is broad-spectrum, and the agent has an effect on a variety of tobacco pests, including stinging and chewing mouthparts. <>

The dosage and frequency of application should be strictly controlled, and other pesticides should be reasonably alternated when using pyrethroid pesticides, and agricultural personnel should wear masks when using pyrethroid pesticides. Avoid contamination of powders and liquids** and eyes. Wash your hands, face, etc. after spraying.

When using, you must choose the right pesticide and the right dosage according to the crop, and you should also wear a mask, gloves and protective clothing, don't use too much at one time, and don't use it in hot weather or rainy weather.

It can be used with other pesticides, with other drugs, with other fertilizers, with pesticides, and with water, these are all ways to use pesticides.

You must not use well water, stay away from water sources, pay attention to the time of use, pay attention to the outside temperature, and also pay attention to the frequency of spraying.

Glad for your question.

You're talking about cyhalothrin.

Also known as kung fu pyrethrin, it is a broad-spectrum insecticide.

One. As for what kind of herbicide you said and about.

Mixed? Most herbicides can be mixed with pyrethroid insecticides, but this is not recommended

1. Insecticides are mainly sprayed on crop leaves and stems, but herbicides are mainly sprayed on weeds and stems. Mixing may result in poor weeding results.

2. Some herbicides are alkaline or acidic, and when mixed with insecticides, they may be antagonistic and affect the effect of weeding or insecticide.

Hope mine is helpful to you.
