In order to ensure a good cotton seedlings, “all seedlings strong” off, cotton seedling disease (blight, anthracnose) prevention and control is an important part of the past prevention and control of these two diseases, mainly by Saracephalus, Xili Health Mercury preparations, but the mercury preparation is highly toxic to human beings.

The first test results are reported as follows:
