What pesticides burn leaves and fruits, and what pesticides have a good effect on the preservation o

I guess you've used a fake drug, emamectin benzoate is a biopesticide.

No, Avi is too, Dysen zinc sterilization.

It is very likely that the one with Daisen zinc is a fake caused by the burning of leaves, look at what brand, it should be more fakes of Daisen zinc in the market.

There are both diseases and insect pests that lead to the dried and sharp yellow leaves of garlic, which may be due to lack of water and drought, and the causes are complex. Early diagnosis, early prevention, and pollution-free prevention and control have good results. You can try to kill insects with plant ash. Or use sterilized yao.

There is no single pesticide that can accomplish these things, and your crops do not know what they are, I will give you a brief analysis: leaf protection: early, that is, before flowering, agricultural spikes and branches need more nitrogen, mainly containing nitrogen, but it is best to feed with fertilizer bridge base, so that the effect is good, the validity period is long, and more potassium-containing pesticides or fertilizers need to be used before and after flowering, mainly strong stems.

Puffed fruit: The pesticides required for puffing fruit of different crops are different! Especially peppers, tomatoes, eggplants, etc., you can go to the pesticide shop Minzu Jinpu to consult! Don't use drugs indiscriminately! To be targeted

As for supplementing nutrients and the like, it is best to use fertilizer, if the land is not lacking in some kind of nutrition, use farmhouse fertilizer to make up, which is effective for a long time, and it is better for crops and land.

The foliar fertilizer produced by Weifang Aofeng has a good effect on leaf preservation, fruit expansion and nutrition supplementation of crops.

First, rinse with running tap water for a few minutes to remove most of the germs, pesticides and other contaminants on the surface of the strawberries. Note: Do not soak in water first, so as not to dissolve the pesticide in the water and then be absorbed by the strawberry and seep into the inside of the fruit.

Soak the strawberries in rice washing water (it is advisable to use the first rice washing water) and light salt water (add half a spoon of salt to the basin water) for 3 minutes, their effects are different, alkaline rice washing water has the effect of decomposing pesticides; Light salt water can make the insects and insect eggs attached to the surface of strawberries float, which is easy to be washed away by water, and has a certain disinfection effect. Then use running tap water to rinse the rice washing water, light salt water and possible harmful residues. Rinse with clean water (or cold boiled water).

The medicine is too strong.

If the pesticide damage is caused by acidic pesticides, some quicklime or plant ash can be sprinkled.

If the pesticide is more harmful, it can also be sprayed foliar with 1% bleaching powder.

For the pesticide damage caused by alkaline pesticides, acidic fertilizers such as ammonium sulfate can be added.

Regardless of the pesticide damage, foliar spraying of potassium dihydrogen phosphate solution or mixed spraying with urea solution and potassium dihydrogen phosphate solution can significantly reduce the loss caused by pesticide damage.

If it is found in time, it can be quickly sprayed with a large amount of water. Spray 2-3 times repeatedly, and loosen the soil to promote root development and enhance crop recovery.

For the pesticide damage caused by some herbicides, appropriate drainage and irrigation can reduce the degree of pesticide damage. For example, the pesticide damage caused by promethonyl can be alleviated or mitigated by immediately draining and replacing the field water in the early stage, and then using measures such as intermittent drainage and irrigation.

After the crop has pesticide damage, comprehensive remedial measures should be taken according to the type of pesticide and the degree of crop damage, so as to reduce the harm more effectively.

High concentrations of pesticides cause vegetables to lose water to be adopted.

The dosage is too strong. Prepare as directed.

The medicine is wrong or the temperature is too high when spraying.

Spray water on the foliar surface and increase the amount of irrigation appropriately.

That's the problem of taking the wrong medicine.

It is estimated that you have used a fake drug, emamectin benzoate is a biological pesticide No, Avi is also, Dysen zinc sterilization, it is very likely that the belt Dysen zinc is a fake caused by burning leaves, look at what brand, it should be more fake Dyssen zinc in the market.

Chlorothalonil is an excellent fungicide, broad-spectrum and low toxicity. Whether it is imported or non-imported, chlorothalonil is easy to cause pesticide damage to plants if it is used improperly.

When actually using it, pay attention to the following points:

Pears, persimmons, peaches and plums are prone to pesticide damage and should not be used. Apples should not be used for 20 days after they have fallen into flower.

Large dosage, high temperature and dry weather are prone to pesticide damage.

If you are not sure, it is best to do a small-scale pesticide damage test first. to ensure the safety of medication.

Please read the product label carefully before taking medication.

It is a scale insect, a cotton white scale. Kill 1000 times with cocoon or 1000 times pesticide synergist. Paramecium or cotton white scale is a wax shell, and the addition of pesticide synergists is to increase adhesion.

Once every 5-7 days, twice is fine. Fertilizer deficiency: watering combined with fertilization.

After the leaves fall in autumn every year, a large fertilizer should be applied once to supplement the nutrients consumed by flowers and fruits, and it is better to apply well-rotted organic fertilizer. At the same time, combined with winter irrigation and watering. Apply organic fertilizer 1 time and water 1 time permeable before spring bud shading.

The super-concentration use of high-lipid film emulsion 80 times liquid, suffocation and burn the leaves, the normal is more than 200 times the use.
