Chlorothalonil

A broad-spectrum, protective fungicide. It has no systemic action, good adhesion, and a long effective period.

It primarily functions as a preventative and protective agent and should be used before or in the early stages of disease development.

2: Application Tips:

Chlorothalonil is not systemic; when applying, it must be sprayed evenly and thoroughly on both sides of the leaves, especially the underside, to ensure effective coverage.

Generally, begin application before or at the early stage of disease, spraying once every 7-10 days for 2-3 consecutive applications.

3: Scientific Use

It is recommended to rotate with fungicides with different mechanisms of action (such as pyraclostrobin, mancozeb, etc.) to delay the development of resistance in pathogens.

Pay attention to the safety interval (the number of days before harvest before application), generally 3-7 days, to ensure the safety of agricultural products.
