White dew and autumn equinox were in September. It was a cool autumn rain. This month, we must pay attention to prevent the autumn cold from cooling, and prevent the damage caused by autumn autumn rain. In the north, the winter wheat is sown. Rape seedlings were sown and crops such as peanuts, sesame, and corn began to be harvested. Autumn vegetables timely planting, nursery, planting. At the same time, good livestock breeding and autumn disease prevention work. In view of the growing planting area of ​​edible fungi in our province, we remind farmers here that we must pay attention to the control of pests and diseases in the cultivation of edible fungi in the fall. 1. Lesion type is dominated by brown spot. There are white hairy hyphae on the surface of fruit body and small spots of ocher. On the top of the mushroom, the mail is shrinking, and some of the mushroom caps are chapped; others are mainly rust spots, and rust-colored spots appear on the mushroom handles and mushroom covers. The main reason is that the humidity in the shed is too large and the ventilation is poor. 2, malformations mainly in the slender mushroom stems, roots developed and thick. The main reason is the lack of oxygen in the greenhouse or poor ventilation. 3. The mushroom-like mycelium produced a large amount of airborne mycelium in the surface of the mycelium, causing the mushroom to appear in a state of leggy. This phenomenon is mainly caused by excessive humidity in the greenhouse, which affects the normal growth of the mushroom. For these several different types, the following measures should be taken to prevent the occurrence of mushroom diseases. First of all, in the cultivation, do not take too much water and control the humidity in the shed. When the humidity is too high, it must be promptly released. In addition, we must pay attention to the purification and rejuvenation of the strains, and sterilization and sterilization of the plants. In addition, some flat mushrooms are harmed by aphids (star spiders), which are mainly manifested in the damage of mycelia and fruiting bodies of flat mushrooms. Individual caps and pleats were also compromised, resulting in the appearance of many yellow concave spots on the surface of the flat mushroom, affecting the quality and appearance of the mushroom. In addition, in the production of Pleurotus ostreatus, the species fly hatches a large number of larvae (also known as quail) after spawning at the base of Pleurotus citrinopileatus, damaging various parts of the Pleurotus ostreatus. Control methods Whether Starscream or flies, they can be sprayed with 18% of Zelkova 400-600 times or 4% of Green Treasure 400-600 times.
