How much water is 20 grams of pymetrozine powder for the control of cabbage aphids, thiamethoxacosta

*To control cabbage aphids, 20 grams of thiamethoxazino powder needs to be mixed with 50 kg of water**.

Here's how to use it:

1.Foliar spray: 15 to 20 grams of 50% pymetrozine water dispersible granules per mu, sprayed with 30 kg of water, to control vegetable aphids, whiteflies, rice planthoppers, leafhoppers and other pests.

2.Root irrigation: 1000 times of 25% pymetrozine wettable powder is used to irrigate roots to control aphids, planthoppers, whiteflies and other pests, and the effective period can reach about 50 days.

Please note that pymetrozine is toxic to fish and some aquatic organisms and should be used to avoid contaminating water sources. At the same time, if you experience any discomfort during use, please seek medical attention in time.

Thiamethoxatrozine is not suitable for the control of cabbage.

Thiamethanpyrmetrozine can remove planthoppers, white-backed planthoppers, gray planthoppers, rice thrips, blackthorn whiteflies, apple aphids, peach aphids, whiteflies, whiteflies, thrips, aphids and other stinging and sucking mouthparts pests of various crops, which has both speed and durability. The effect is significantly better than that of imidacloprid and acetamiprid.

Thiamethoxine is a microtoxic insecticide mixed with the systemic insecticide thiamethoxam and the non-killing insecticide pymetrozine with systemic and contact killing effects, which has a good control effect on rice planthoppers and wheat aphids.

Pymetrozine is a representative of pyridine heterocyclic insecticides and has a unique mode of action. Studies have shown that as soon as an aphid or planthopper comes into contact with pymetrozine, it produces a needle-blocking effect, stops feeding immediately, and starves to death, and this process is irreversible. Therefore, pymetrozine has excellent ability to block insect poisoning.

The main features of pymetrozine:

Pymetrozine is a highly selective contact insecticide with good systemic activity. In plants, it can be conducted in both xylem and phloem; Therefore, it can be used both as a foliar spray and as a soil treatment. Due to its good conduction properties, the newly grown branches and leaves can also be effectively protected after spraying the stems and leaves.

How to use pymetrozine.

1. Root irrigation: pymetrozine has good systemic activity. In the plant can be both xylem and phloem conduction, planting, with 25% pymetrozine wettable powder 1000 times liquid irrigation, can effectively control aphids, planthoppers, whiteflies and other pests, the effective period can reach about 50 days.

2. Spray: to control vegetable aphids, whiteflies, rice planthoppers, leafhoppers and other pests, 15 to 20 grams of 50% pymetrozine dispersible granules per mu, after the medicine, the pests are fed, the death rate is slow, the average is about 60% after 3 days after the medicine, and it can reach more than 95% 7 days after the medicine. And it lasts for more than 25 days.

Pymetrozine is widely used in vegetables, wheat, rice, cotton, and fruit trees. Prevention and control objects:

Aphidaceae, planthoppers, whiteflies, leafhoppers and other pests, such as cabbage aphid, cotton aphid, wheat aphid, peach aphid, small green spotted leafhopper, brown planthopper, gray planthopper, white-backed planthopper, sweet potato whitefly and greenhouse whitefly, etc.

Generally speaking, the concentration of 100 grams of thiamethoxam mixed with water to control aphids should be applied in 2000 3000 times, that is, 100 grams multiplied by 3000 times, which is 300000 grams = 300 kilograms, so it should be mixed with 300 kilograms of water.

What 30% of thiazine, 100 grams of pyroxam suspension you are talking about, how many kilograms of water are mixed with aphids to control aphids? At least a few hundred kilograms or more for whom?

Summary. 50% pymetrozine belongs to pyridine insecticides, belongs to a new nicotinoid insecticide, has contact killing and stomach toxicity, but also has osmotic activity, mainly to control aphids, thrips and other pests of stinging mouthparts, under normal circumstances, 50% pymetrozine mu with a dosage of 8-10 grams of mu, with water 30-40 kg mu spray, so 50% pymetrozine dilution multiple should be 2000-3000 times liquid spray.

50% pymetrozine belongs to pyridine insecticides, belongs to the new type of nicotinine insecticides, has contact killing and stomach toxicity, but also has osmotic activity, mainly to control aphids, thrips and other pests of stinging and sucking mouthparts, under normal circumstances, 50% pymetrozine per mu with a dosage of 8-10 grams of mu, with 30-40 kg of water spray, the mold deficit with 50% pymetrozine dilution factor should be 2000-3000 times liquid spray.

2000-3000 times with water.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: can pyritrazine be used on cabbage:

Enzidinepymetrozine can be used on cabbage. It is recommended to spray enenylpyritrazine or clothianidin for control. Chinese cabbage aphids can be controlled with 20% Actay (thiamethoxam) with high efficiency and low residue.

Cabbage aphid damage, pymetrophides can be used. Dinotefuran, bifenthrin plus imidacloprid, bifenthrin plus acetamiprid, endinotefurin, thiamethoxam, ethyl spinosad for control. Chinese cabbage aphids are well controlled with imidacloprid or enylpymetrozine.

Neonicotinoids such as imidacloprid, acetamiprid, and thiamethoxam are all OK. Chinese cabbage aphids have occurred with imidacloprid control effect.

Clothianidin can be used in a few leaves of cabbage, this is not a serious and strict requirement, as long as there are mold potato manuscript aphids on the cabbage, then it can be used normally.

It's just that in the different growth stages of cabbage, there are certain requirements for the ratio and dosage of drugs. If the cabbage grows relatively large or late, then you can increase the proportion, which can be selected according to the actual situation of the cabbage.

Summary. Dear, clothianidin is diluted 1000-1500 times to fight whiteflies effectively, and it is best to use 2-3 times at an interval of 7 days.

How to pre-split fruit during tomato veraison.

1) Reasonable ventilation to avoid excessive temperature difference between day and night in the shed, the ring crack of tomatoes is similar to the skin of cucumbers, and wait for the dew on the surface of the fruit to disappear before releasing the wind, which can be effectively avoided. It is recommended that vegetable farmers prepare Zheng Wu when the temperature reaches 27-28, and then ventilate after the fruit surface dew subsides, which is conducive to reducing the rolling of the tomb and rarely cracking the fruit. In windy weather, it is necessary to avoid the wind blowing directly on the tomato fruits, which can also effectively reduce fruit cracking.

2) Pay attention to water and fertilizer management, keep the soil moist in the early stage of fruit expansion, avoid flood irrigation, control the humidity in the shed, and do not dry and wet. It is better to "water with small water frequently", and try to avoid uneven drought and flood to prevent the occurrence of fruit cracking.

3) Pruning and pruning should pay attention to leaving more side branches, hitting side branches at night, leaving a leaf on each side of the branch and pinching the tip to ensure that the plant has more growth points and functional leaves, this method can significantly improve the birth of tomato cracked fruits. (4) Pay attention to the concentration and timing of spraying and disease prevention. The spraying is selected from 9 a.m. to 11 a.m., after the fruit surface is dewed, and the spraying is avoided at noon high temperature time.

Spraying calcium fertilizer at the fruit expansion stage can prevent fruit splitting. OK.
