There are new ways to control wheat scab and powdery mildew
Wheat scab, which is also known as wheat ear blight, rotten wheat head, and red wheat head, is one of the major diseases of wheat. There have been fewer effective control measures.
Wheat powdery mildew is a worldwide disease, and it is distributed in all major wheat producing countries. China's Shandong coast, Sichuan, Guizhou, and Yunnan are widespread and the damage is heavy. In recent years, the disease has become increasingly serious in the northeast, north and northwestern wheat districts. The disease can invade the various organs of the wheat plant above ground, but it is mainly leaves and leaf sheaths. When the disease is heavy, the glume and awn can also be affected.
Biopesticides, tetramycin, have been formally registered by the Ministry of Agriculture for both wheat disease prevention and control and have a good reputation among wheat growers. Tetramycin is characterized by strong systemic penetration, broad bactericidal spectrum, and safety to crops. It also has the characteristics of promoting crop growth, high efficiency, no phytotoxicity, and no pollution to the environment. It can prevent and control invading bacteria in deep layers of crops. The prevention and control of a variety of crop diseases, in line with the advantages of bio-pesticides, such as safety, high efficiency and strong pertinence, has achieved the perfect combination of plant protection and environmental protection.
Tetramycin is a metabolite of Streptomyces non-hygroscopicus, which forms a variety of nutrients that can be absorbed and utilized by crops during the fermentation process. It has the function of promoting the healing and regeneration of crop tissue after trauma, enhancing the photosynthesis of crops, and increasing the yield. .
