Method for preventing and treating rice wheat sheath blight using no-leaf spray of Validamycin

Abstract

A method which adopts jinggangmycin non-foliage spray to prevent and control sheath blight of rice and wheat belongs to the method which prevents rice and wheat diseases, and solves problems existing in other technologies. The method of the invention is as follows: when a field is ploughed, 200g of 20% of jinggangmycin is added with 15kg of water per mu, dissolved fully and stirred evenly, and 25kg of grass meal, sawdust and chaff, or 50kg of sandy soil is mixed with a fertilizer to obtain a mixture, and then the mixture is scattered on the surface of the field, and ploughed in the soil. For 3 years, the method is applied as a demonstration by 6000 peasants in 100 villages of 13 towns, and achieves the preventative effect on the sheath blight of the wheat and the rice.

Description

1. Technical field: [0001] The invention relates to a method for preventing rice and wheat diseases, in particular to a method for preventing and controlling rice and wheat sheath blight by non-foliar spraying of Jinggangmycin. 2. Background technology: [0002] A kind of sheath blight of wheat and rice in recent years has become a common disease in my country's wheat and rice planting areas, seriously affecting the normal growth of wheat and rice. The commonly used agricultural control measure for many years is to use 20% of 25 grams of Jinggangmycin mixed with 75 kg of water per mu to spray the leaves at the early stage of the disease. , cannot be sprayed evenly to the diseased site sufficiently, and the effective control effect cannot be achieved, leading to the spread of the disease, resulting in a very common phenomenon of production reduction. 3. Contents of the invention: [0003] The object of the present invention is to provide a kind of non-leaf spraying method ...
