What should I pay attention to when using trichlorfon?

Trichlorfon is the oldest organophosphate insecticide in China, its toxicity is low, the insecticidal spectrum is wide, the first is low, in China's agricultural production and health pest control has played a major role, but due to years of use, many major pests (such as cabbage worm, cabbage moth) have produced serious resistance, almost ineffective varieties. However, in some areas that have been out of service for many years, resistance to certain pests has faded. In recent years, it has been found that trichlorfon has a certain effect and still has use value, especially for the control of underground pests.

Commonly used in agriculture there are the following 3 dosage forms: 80% crystal trichlorfon, the commodity is white crystal block, difficult to crush and weigh, difficult to dissolve directly with water, before use with 50 warm water (up to 70) to dissolve the weighed dose into the mother liquor, and then add water to dilute into the spraying solution; 80% trichlorfon soluble powder, which is an improved new dosage form, can be directly diluted with water when used, more convenient, the control of general vegetable pests (Lepidoptera, Coleoptera, Tasseloptera, etc.) using 1000 times liquid spray, the prevention and control of underground pests can be used 1000 times liquid irrigation; 5% trichlorfon powder is mainly used for soil treatment before sowing (2 3 kg mu) or soil surface spreading or furrow application when underground pests are rampant. This agent has low toxicity, and is easy to decompose in nature, with small residue and less pollution, and is suitable for vegetable fields.

However, beans, sorghum, corn, and apples are sensitive to this agent, which is easy to cause pesticide damage and should not be used. In addition, because this agent is easy to hydrolyze and fail, it is used as a spray diluted into a liquid medicine, which should be prepared and used now, and should not be used for a long time after mixing. According to the national standards for the safe use of pesticides, trichlorfon should be stopped 7 days before the harvest of vegetables.

It should be used and matched, and it cannot be stored for a long time, otherwise it is easy to decompose and fail. When using the liquid medicine of crystal trichlorfon or wettable powder as a spray on stems and leaves, it is advisable to add a neutral laundry detergent with a liquid amount of medicine to increase the wet spreading performance of the liquid medicine on the stems and leaves, so as to improve the efficacy. The alkaline toxicity of trichlorfon increases, and it is not advisable to wash hands with soap after application, and should be rinsed with water.

Trichlorfon has a corrosive effect on metal, and the sprayer should be washed with clean water after spraying to prevent corrosion. This agent has strong hygroscopicity and should be stored in a ventilated, dark, cool and dry place.

Another name for it is:DichlorvosThe method used is mixed with water, and the method is used by spraying. Generally, when we buy this pesticide, he will have a manual, and the instructions will clearly state how to use Glory. For example, like this dichlorvos, it has a manual on it, how much is it used per mu?

And how many kilograms of water should be mixed for spray control. Generally, some dichlorvos powder can effectively kill some insects, such as this flying insect, and some leaf insects, beetles.

Ah, they can be effectively killed. <>

However, we must understand the instructions clearly before blending, see how many kilograms of water should be blended with 100 grams or even 50 grams of dichlorvos, not too much, too much will waste pesticides, of course, the concentration can be appropriately higher, but not too large, within 5% can be. To give a simple example, 100 grams of dichlorvos solution requires 100 kg of water, then we can mix 95 kg of water. It should be noted here that if dichlorvos is used to spray this vegetable, then its safety interval should not be less than a week, and it will not be picked until 7 days later.

If you want to use dichlorvos to kill some swans, mulberry caterpillars, or some butterflies, then the concentration is different. Some insects have stronger resistance and are a little larger, so this concentration should be increased at this time, for example, a pound of pesticides should be equipped with 100 pounds of water, so as to effectively kill those pests of butterflies. <>

Finally, you can choose to mix it with food to kill it。If some insects are in the ground, then you can use some wheat bran.

Ah, or some cornmeal.

Add some flour, add this dichlorvos and stir well, sprinkle on this ground or sprinkle it in the place where this insect is often infested, it can also effectively kill insects. Because these pests will crawl out and eat these corns, as well as flour, it will be easy to be poisoned after eating, so as to have a killing effect.

For the control of rice borer, rice leaf miner fly, rice iron beetle, 150 200 grams of 80% trichlorfon soluble powder per mu, mixed with 75 100 kg of water to spray rice. For the prevention and control of vegetable tobacco insects and yellow gourds, 80 100 grams of 80% trichlorfon soluble powder per mu are used for spray control with 75 100 kg of water. It is used for the control of onion maggots, radish maggots, cabbage maggots, and trichlorfon mixed with water 1000 1500 times for root irrigation control.

The way to use it should be with water, and then combine it according to a certain proportion, and then put it in a watering can to spray on the plants we need to exterminate, or spray on some crops, all of which have an insecticidal effect.

The use method is very simple, first of all, we should pay attention to the ratio and dosage, and then we must prescribe the right medicine, avoid rainy or windy weather, choose to spray on sunny days, and wear protective clothing in the process of spraying to avoid injury.

To choose the right pesticide according to the crop, you should also pay attention to the appropriate concentration, you also need to dilute it with water before use, and you should also pay attention to the way of spraying, do not use too much at one time, and you should also pay attention to the efficacy.

Trichlorfon mainly has a strong stomach toxicity effect on pests, and has a contact killing effect on pests, and trichlorfon has permeability to plants, but has no systemic conduction effect. Trichlorfon can control chewing mouthparts pests, livestock parasites and cleaning pests on rice, wheat crops, vegetables, fruit trees, cotton and other crops.

It is used to control inchworms, moths, leaf rollers, whiteflies, leaf wasps, grass borers, weevils, jasmine leaf borers, leaf miners, poison moths, stinging moths, lamp moths, armyworms, mulberry caterpillars, butterflies, longhorn beetles and other young larvae, and can use 90% trichlorfon crystals mixed with water 1000 times liquid for spray control.

Precautions for the use of trichlorfon.

When trichlorfon is used, it should be turned into water and should not be impurified. When pouring water, use a few boats of water and try to be as even. When using it, the water body should be strictly calculated, so that the river crab can be prevented from serious injury.

After the use of trichlorfon, you can add some water the next day, if you find that there is a soft shell crab damage, it means that the amount of use is large, and the next day you will use 100 poisons to detoxify, specifically for trichlorfon and organophosphate detoxification. If the soft-shell crab is not found, it can be detoxified on the third day. Then disinfect with crab and finally cultivate bacteria and adjust the water.

Trichlorfon is a high-efficiency, low-toxicity and broad-spectrum insecticide, which has a strong stomach toxicity and contact killing effect. Commonly used dosage forms are % crystals, % wettable powders and powders, etc.

It is effective in the control of pests such as Diptera, Lepidoptera, Coleoptera, etc., and is mainly used to control chewing mouthpart pests. Spraying 1000 1500 times of water with 90% crystals can control inchworms, poisonous moths, stinging moths, biscularized moths, canopy caterpillars, moths, pine caterpillars, goldenrod insects, beetles, weevils, leafhoppers, leafhoppers and other pests; 50 grams of 90% crystals and 1 2 kg of water are used to mix 10 20 kg of seeds, which can control underground pests such as mole crickets and needleworms; Use 1 part of 50% trichlorfon wettable powder, dissolve it with a small amount of water first, and then mix it with 50 parts of fried cottonseed cake, wheat bran and other substances, and sprinkle it on the surface of the ground in the evening to trap and kill pests such as tigers and mole crickets; Watering the roots of seedlings with 90% crystals 1000 times can control underground pests such as grubs and seed fly larvae.

There is a difference, the two are two different drugs.

The main ingredients of chlormonocide are ivermectin, praziquantel, albendazole, synergist, and long-acting sustained-release agent. Because it is harmful to a variety of parasites in and out of poultry and livestock.

and eggs have a strong killing effect, can be used to drive cattle, sheep, pigs and economic fur animals of a variety of in vitro parasites and eggs.

Trichlorfon is an organophosphorus insecticide, which is widely used in agriculture, mainly for the prevention and control of cabbage insects and cotton leaf jumping insects.

Mulberry silkworm, mulberry yellow.

Weevils, fruit tree leaf wasps, fruit flies.

and other pests. Refined trichlorfon can be used to control internal and external parasites in pigs, cattle, horses, mules and livestock, and is effective against household and environmental health pests. It can be used for schistosomiasis, and is a good multi-effect insect repellent in animal husbandry.

Trichlorfon is a highly effective and low-toxicity organophosphate insecticide. White crystals, slightly odorous, soluble in water. Under the condition of weakly acidic pool water, the properties are stable, and it is highly toxic when decomposed by alkali.

This is the inhibition of cholinesterase activity, which can lead to neurological diseases and the elimination of insect and crustacean poisoning. Here are a few things to keep in mind when using trichlorfon:

1. Trichlorfon is the preferred drug for parasiticide. It has a strong effect on ringworm, cryptowhipworm, needleworm, fish lice, and larvae of Jiujiang head worm;

2. Trichlorfon is acidic and weakly alkaline to the pool water, and the pH value is above 7, so it is not suitable for use;

3. Trichlorfon can be dissolved in pond water and can be used after dissolving. Not suitable for long-term storage; <>

Crystalline trichlorfon, the dosage of the whole pool is; The disinfection dose of fish is 20-30ppm, and the disinfection time is 15 minutes; Mix with feed, the dosage is 1:300, and feed continuously for 5-6 days;

5. Trichlorfon is particularly sensitive to mandarin fish, sea bass, pomfret and other fish, so it should not be used;

6. In case of an accident when using trichlorfon, pour 6-8 bottles of atropine per 667 square meters of water in the whole pool to detoxify and residual toxin. <>

Trichlorfon belongs to organophosphate preparations. If you encounter alkaline drugs or alkaline substances, it can increase toxicity, cause poisoning in livestock, and even lead to death. Sodium bicarbonate, artificial salt, stomach powder, sodium salt of various sulfonamides, soft soapy water, hard soapy water, lime water, etc. are all alkaline drugs, which should be avoided in combination with or at the same time with "trichlorfon".

It is a broad-spectrum anthelmintic drug, which also has a killing effect on a variety of nematodes and a variety of ectoparasites in livestock and poultry. It's inexpensive and easy to use. However, if too much trichlorfon is used, it is toxic to people and livestock.

Poultry is more sensitive to trichlorfon and is not suitable for application; This is followed by cattle, horses, pigs, and sheep that are less susceptible. Trichlorfon has a good killing effect on ectoparasites in livestock and poultry. For sheep rhinoceros larvae, 50 70 mg per kg body weight can be taken orally as a 2% aqueous solution, or 20 60 ml of 2% trichlorfon solution can be sprayed into the nasal cavity of sheep with a syringe.

Dichloride should be used according to the actual situation of the crop, if there are many insects, the amount should be increased, and the harvest crop should not be used.

First of all, it is necessary to adjust the pH according to the crops, and then dilute it with water in advance, do not dilute it with river water, and it must be particularly uniform when spraying, and then it must be kept away from water resources, and it must be kept away from lotus ponds.

Be sure to dilute it, determine the amount of drug used according to the actual situation, choose the appropriate method to use, and you can choose to splash, which also has a good effect.

The rational use of trichlorfon mainly pays attention to the following points:

1) The use of trichlorfon to control parasitic fish diseases, should be appropriately adjusted according to the pathogen object and water quality pH value, when the water pH value can be slightly increased, the pH value can be reduced when the dosage can be reduced.

2) In order to improve the effect of fish disease prevention and control and reduce drug resistance, it should be used in rotation.

3) When applying trichlorfon, alkaline substances should not be added or washed with alkaline water to prevent the formation of more toxic methoxydichloroethylene phosphoric acid and avoid animal and fish poisoning.

4) Trichlorfon is acidic, do not use metal containers when spraying, so as to avoid corrosion; If a metal sprayer is used, it must be washed with water in time after use.

The use of the enemy hundred kills includes the right time and weather, the right dose, the right equipment, the safety of use, precautions, etc.

First, the use of the steps

Find a nest or hiding place for pests. Spray Dimex on areas of activity and possible hiding places for pests. You can use a sprayer, a watering can, or direct spraying.

Be careful not to spray on items such as food, kitchen utensils, and pets. It usually takes a few minutes to a few hours for the enemy to do its job. Clean up dead pests and anti-clay residues.

2. The right time and weather

The best time to use Enemy Kill is in the early morning or on a sunny day. Avoid using it on rainy days, as the rain will wash away the sprays on the plants. It is more effective to use Trichlorpectin in the early and middle stages of crop growth.

It is usually better used in weather conditions with less wind, lower temperatures, and higher humidity.

3. Measure the agent

According to the recipe on the product leaflet, mix Trichlorpectin with an appropriate amount of water. Be careful not to exceed the recommended dosage. When used on fruits, vegetables, vegetables and other crops, the enemy is generally killed and water in accordance with only Shenchang 1:

1000 ratio mixing, that is, 1 gram of enemy kills per 1 liter of water. When used on flowers, greening and other plants, it is generally mixed with water in a ratio of 1:2000, that is, every 1 liter of water is added to defeat the enemy.

4. Use a sprayer to spray

The agent is placed in a sprayer and sprayed on the leaves, stems, and flowers of the plant. The sprayer should be kept at an appropriate distance from the plant to ensure that the agent is evenly covered on the plant.

5. Pay attention to safety

When using the enemy, you should wear personal protective equipment such as filial piety protective clothing, gloves, and masks to avoid direct contact with the drug**, mouth, eyes and other parts. Pay attention to cleaning the sprayer and protective equipment after use.
