Thiram

If Thiram is used reasonably, it will have a great effect on Sclerotinia. However, with this medicine, on the tomato, it is easy to appear dry tip, special dry leaves. Appear once at a time.

Copper ammonia

Copper ammonia is relatively safe, but this drug has a fatal shortcoming. Spraying on the eggplant leaves sprays in the afternoon. On the second day, the leaves appear wilting and gradually return to normal on the third day. This medicine beats the bacterial spot effect of eggplant, which is much better than other copper preparations.

Glyphosate

Glyphosate, a herbicide, but it also has weaknesses, low temperature and dead grass.

Acridine

Acetam mites, a common drug used to fight mites, this drug is very sensitive to temperature, high temperature, and good insecticidal effect. When the temperature is low, the effect is worse. It doesn't matter in the shed, you can pay attention to the temperature of the medicine in the open air.

Mancozeb

The experienced vegetable growers know that if a pesticide containing mancozeb is sprayed on the eggplant, the leaves of the green oil will become dull, and the leaves in the middle and lower parts of the plant will become old and yellow, and some will be yellow. If used continuously for several times, it will cause serious defoliation.

The reason is that the pesticide contains a large amount of manganese, and the eggplant is particularly sensitive to manganese. After spraying, the manganese element accumulates in the leaves, so that the manganese is excessive, the light leaves are yellow, and the heavy ones start from the top. .

Anyone with mancozeb has side effects in this regard. Therefore, once the yellow leaf phenomenon of eggplant is found, it is first considered to be caused by spraying mancozeb, and should be stopped immediately, and then sprayed with sodium nitrophenolate or brassinolide.

Paclobutrazol

Since the half-life of paclobutrazol into the soil is as long as 6-12 months, and it is not easy to decompose, it will directly affect the growth of the sorghum vegetables. Taking eggplant as an example, planting in the soil containing paclobutrazol will directly affect the rooting and lowering of the eggplant roots, and the roots are not deep, and the roots are not strong.

The correct method should be that the effect of foliar spray control is better, and the safety is higher. After the harvest in the season, the paclobutrazol is not easy to affect the crop. In addition, even if foliar spray of paclobutrazol occurs, it can be relieved with 25-250 ml/kg of gibberellin solution, which is difficult to remedy. Therefore, it is best not to apply paclobutrazol!
