Lu Xiaoli, a reader of Lianyungang, came to the telephone and said that they used copper sulfate and other agents to control the moss in the paddy fields and the effect was not very good. Now I see the Jiangsu Agricultural Science and Technology News that the moss net can control the moss in the pond. She wants to use this medicine to control the moss in the rice field. She asked if the net moss can be used in paddy fields and where to buy the product. Is there any other way to control the moss in rice fields? According to investigations, 20% Moss WP is the first WP approved by the Ministry of Agriculture for the prevention and control of moss (ie, Spirogyra). It is highly efficient, low-toxic and has outstanding control effects on mosses in paddy fields. At the same time, it can control some weeds and protect seedlings. The drug is manufactured by Shenyang Xingong Chemicals and Pesticides Factory in Liaoning Province. To control moss in paddy fields, we can also take the following measures: (1) Change water frequently and clean water. (2) Phosphatic fertilizer is used as base fertilizer and should not be used as surface fertilizer. (3) Chemical control. Use 50% paracetamol WP 50 grams per acre, mix 20 kg fine soil, plant the alfalfa live shallow water after spreading, keep 3-4 cm water layer for 5-7 days, leakage paddy fields, rice fields after jointing is forbidden. Or use 24% gourd emulsifiable concentrate 20ml per acre, mix 20kg fine soil, spread water 1 week after planting hoe, keep 3-4cm water layer 5-7 days, small seedling field should not be applied, dew is not dry or leaves spit water Can not be used to prevent phytotoxicity.
