The Control Test of Different Fungicides on Mulberry Sclerotium Disease

At present, popcorn disease of mulberry sorosis is a great disadvantage to the development of mulberry. In order to control popcorn disease of mulberry sorosis effectively and produce non-pollution mulberry, it is very imperative to screen some pesticides with high activity, low toxicity and low residue. Field experiment was carried out to investigate five pesticides with low toxicity and low residue, treated with 3 concentration gradients. The result shows that 800～1200 times liquid of 70% thiophanate-methyl wettable powder and 500～1 000 times liquid of 50% carbendazol wettable powder had good control effects. Alternative use of 400～600 times liquid of 50% procymidone and thiophanate-methyl or carbendazim had control effects and no obvious phytotoxicity.
