How to control rice blast?
(1) Seed treatment
Rice seeds should be selected from disease-free or lightly diseased fields.
(2) Selection of disease-resistant varieties
The selection of disease-resistant varieties is an effective measure to control rice blast, and is also a key measure for integrated control.
(3) Strengthen planting management
Ensure basic fertilizer and reasonable application of nitrogenous, phosphate and Potassic fertilizer to promote healthy rice growth, together with water management to create environmental conditions unfavourable to rice blast.
(4) AXTAR TOP 333 SC Fungicide use
A fungicide that has a good effect of lipid solubility, protective, therapeutic activity, quite suitable for resistance manage-ment and integrated disease control.
We do lots of field test prove that the AXTAR TOP 333 SC has a high effect.
