How is trichlorfon used?

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.

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.

<> trichlorfon. It is an organophosphorus insecticide, the insecticidal effect is relatively good, and there are many ways to use trichlorfin insecticide, such as seed dressing, pouring watering, soaking, fumigation, spraying, powder spraying, withdrawal, etc. Among them, it can be sprayed with 1000 times of 90% crystal trichlorfon to control moths, leaf-rolling moths, whiteflies, leaf wasps, and elephants.

A. Jasmine leaf borer and other pests, use 90% trichlorfon crystals 1000 times liquid to water the roots of flowers and trees to prevent and control grubs.

Noctuidae exigues, white sac moths, etc.

Trichlorfon insecticides mainly kill a variety of pests such as cabbage insects, cotton leaf jumping insects, mulberry yellow, mulberry silkworms, fruit tree leaf bees, weevils, fruit flies and so on.

Trichlorfon insecticides mainly kill a variety of pests such as cabbage insects, cotton leaf jumping insects, mulberry yellow, mulberry silkworms, fruit tree leaf bees, weevils, fruit flies and so on. Flukes, nematodes, echinocephalus parasitic in and out of fish, and cladoperans, copeperans, mussel hook larvae, water centipedes, etc., which are parasitic in and out of fish.

Hazards of trichlorfon pesticides:Trichlorfon insecticide belongs to organophosphorus insecticides, and it is forbidden to use alkaline solution to gastric lavage when poisoning, because the alkaline gastric lavage will cause a chemical reaction of trichlorfon insecticides and produce more toxic dichlorvos. Dichlorvos is highly toxic, the damage to the human body is very great, and it will be life-threatening in serious cases, so it is forbidden to use alkaline solutions for gastric lavage when dichlorfon insecticide poisoning, such as sodium bicarbonate solution.

Be sure to pay attention to the ways and means, wear protective gloves and protective clothing when spraying pesticides, do not expose the ** to the outside, and do not touch your eyes with your hands. It is best to choose the time after 5 p.m.

First of all, we must pay attention to the concentration, and we must pay attention to the dosage, do not use too much at one time, and at the same time, we need to dilute it with water in advance, and we must pay attention to the concentration used, do not use blindly, and do not mix all pesticides together.

The problem with using this pesticide should be that it must be used with gloves, and then it can be diluted with water and not sprayed on the flowers.

After <> diluted with water, trichlorfon insecticides should be prepared and used immediately, and should not be left for a long time.

Vegetables can be sprayed with 1000 times of trichlorfon insecticide, and drugs are prohibited 7 days before harvest.

For apples, corn, sorghum, beans and other crops, it is necessary to use trichlorfon insecticides with caution, otherwise it is easy to cause pesticide damage.

If trichlorfon insecticide is to be used on livestock, the weight should be determined before use, and then the dosage should be calculated according to the weight, too much dosage will lead to poisoning or death of livestock.

1. Contraindications for the use of trichlorfon insecticides

1. After dilution of trichlorfon insecticide, it should not be placed for a long time, and it should be prepared and used immediately.

2. When used on crops, 1000 times of trichlorfon insecticide can be sprayed (about 1000 times). 7 days before the vegetable harvest, the use of the drug is prohibited.

3. Apples and corn are more sensitive to trichlorfon insecticides, and sorghum and beans are very sensitive to trichlorfon insecticides, which are easy to produce pesticide damage after use.

4. The first dose of trichlorfon insecticide is relatively close to the poisoning dose, when used in livestock, too much dosage will cause poisoning and even death, in order to ensure the safety of livestock, the weight should be determined before medication, and then the dosage should be calculated according to the weight.

5. Trichlorfon insecticides can not be used on chickens, ducks, geese and other poultry, because the drug belongs to organophosphorus preparations, and common poultry are more sensitive to organophosphorus preparations, and it is easy to cause harm after use (organophosphorus preparations can infringe on the brain of birds, and will cause neurological disorders after entering the poultry body, and at the same time, the hydrolysis effect of organophosphorus preparations on poultry is weak, that is, the natural detoxification ability of organophosphorus is relatively low).

6. Trichlorfon insecticide can not be used in combination with alkaline drugs, or at the same time, if it comes into contact with alkaline drugs or alkaline substances, the toxicity will be enhanced, resulting in poisoning or death of livestock.

7. Lime water, soft soapy water, hard soapy water, artificial salt, stomach powder, sodium bicarbonate, and sodium salts in various sulfonamides are all alkaline drugs, which should be avoided in combination with trichlorfon insecticides, or used at the same time, and ordinary alkaline hard water cannot be used to prepare trichlorfon solution.

Second, the use of trichlorfon insecticides

1. Allium maggots, radish maggots, and cabbage maggots: During control, use 1000-1500 times of trichlorfon insecticide to irrigate the roots.

2. Pests such as vegetable tobacco worms, yellow gourds, and yellow striped beetles: during control, 80-100 grams of 80% trichlorfon soluble powder mixed with 75-100 kg of water per mu, and then sprayed. The safe interval for the use of trichlorfon in vegetables should not be less than 7 days.

3. Young larvae such as whiteflies, poisonous moths, stinging moths, butterflies, and longhorn beetles: during control, dilute 90% trichlorfon crystals with water into 1000 times of liquid, and then spray.

4. Pests such as rice planthopper, rice borer, rice leaf roller: during control, 150-200 grams of 80% trichlorfon soluble powder mixed with 75-100 kg of water per mu, and then spray the rice. The safe interval for the use of trichlorfon in rice should be greater than 7 days.
