On the afternoon of May 21, Xie Duanyun, an old man from Gaowangcun, Xialou Town, Lingbi County, came to the newspaper office to report a wide range of diseases in the local wheat. Xie Laohan brought more than a dozen sick wheat. The reporter then followed him to the province. The Plant Protection Station consulted experts. After expert consultation at the scene, it was judged as full-blown wheat and head blight. Experts stressed that wheat full-blown disease and scab disease are very important in prevention and are now hopelessly salvaged.
There are two manifestations of sick wheat brought by Xie Duanyun: one is all withered, and it dies from root to ear; the other is that although the leaves are blue, the ears are not strong and dry. “We have nearly 20% of the nearly 2,000 acres of wheat in our village. We do not know what the disease is.†Xie Duanyun said. Liu Jiacheng, deputy director of the Provincial Plant Protection Station, after careful identification, determined that the first case of wheat was full-blown disease, and the second case was head blight.
Liu Jiacheng told reporters that wheat full-blown disease is also known as wheat blight and black foot disease. Full-bleeding disease is a root disease that only infects the 1-2 roots of the root and stem base. In the seedling stage, the diseased plants were short and the lower yellow leaves were numerous, and the seed roots and stems in the ground turned grayish black, and when they were serious, the wheat seedlings were dead. 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. Fusarium head blight is common in the world, mainly in wet and semi-humid areas, especially in temperate areas where the climate is humid and rainy. From the seedlings to headings can be affected, mainly caused by seedlings, stem base rot, culm rot and ear rot, of which the most serious is the ear rot. “The current best time for the prevention of full-blown wheat and head blight has passed and it is now hopeless.â€
How can these two diseases be prevented? Liu Jiacheng told reporters that along the Huai River and its areas south of the common scab within the early stages of wheat flowering timely preventive, if the wheat flowering season in the central and northern regions of Huaibei encounters continuous rain or foggy weather (according to the weather forecast), advance drug prevention. Farmers can spray pesticides in the early flowering period (10% of Yanghua) in time. If the rainy days or the foggy weather occurs, they should be supplemented once every 7 days or so. Can choose penetrants that have good permeability, rainwater washability, and good persistence, such as 15 grams of active ingredient prochlorant, 50 grams of cyanocaverate, or 70 grams of thiophanate-methyl, or 36 acres. % Carbendazim Triazolinone suspension 100 g. The motorized sprayer dispenses 15 kilograms per mu and the manual sprayer sprays 30-40 kilograms evenly.
The prevention of wheat's full-blown disease advocates the use of 2% licorice seeds with a seed weight of 0.2% for seed dressing, with an efficacy of about 90%. Serious block with 3% difenoconazole seed coating agent (Hua Dan) 80 ml, watered 100-150 ml, mixed with 20-25 pounds of wheat seed, can be sown after drying can be stored and then sown.

Many farmers have consulted the newspaper: Can wheat eaten with scab? Can it be used as feed? According to Cao Chengfu, an expert from the Provincial Academy of Agricultural Sciences, the wheat people who have been exposed to head blight are inedible and prone to poisoning. It is also not recommended to use animal feed. It is better to get scorched wheat or to destroy it.
