Thiram, also known as metalaxyl, is a broad-spectrum systemic micro-toxic fungicide with systemic, preventive, and curative effects. It was originally developed by the Japanese company Showa Denko. It can effectively prevent a variety of crop pests and diseases. In summer, with high temperatures and abundant growth of vegetables and fruits, malnutrition and growth disorders often occur. Root irrigation can effectively help the growth of vegetables and fruits. So, can metalaxyl be applied by root irrigation?

Can metalaxyl be applied by root irrigation?

Metalaxyl can be applied by root irrigation, but it should be decided according to the growth status of the crop, and not to irrigate blindly, which may affect the normal growth of the crop.

How to carry out scientific root irrigation?

1. Root irrigation time: Generally, a unified root irrigation should be carried out after the transplanted vegetables and fruits have emerged, with common fertilizers including metalaxyl, chlorothalonil, triazolone, root health, metalaxyl, thiram, or carbendazim. The concentration of medication should not exceed 1500 times theoretically. During the operation, it is sufficient to dilute the concentration on the fertilizer bag by half, and 6-8 buckets of water are usually enough for 3000 seedlings.

2. Selection of root irrigation medicine: If you want to prevent pests and diseases with fertilizers, you can choose the broad-spectrum fungicides listed above. However, after the onset of the disease, medication should be used for specific fungicides. For example, for the wilt disease of hot peppers, you can use metalaxyl, carboxin, or root health or metalaxyl for root irrigation.

Common problems with root irrigation: It is not necessary to water before fertilizing the roots, nor is it necessary to water immediately after irrigation. It is best to water at least 3 days after irrigation so that the antibacterial and disease prevention effect will be better. If there are no serious pests and diseases, 1-2 irrigations after seedling emergence are enough. After the occurrence of pests and diseases, the frequency of medication should not exceed five times. If the pests and diseases are not cleared after five applications of medication, there is no need to continue root irrigation.

Metalaxyl can be applied by root irrigation, and it can also be used for the prevention of other pests and diseases, with a relatively wide range of applications. It is best to read the instructions before using it.
