First, symptoms and identification
The corn sheath blight, also known as "flower stem", has become a major disease of corn due to the inflow of northern varieties in recent years.
The disease mainly occurs on the leaf sheaths and leaves of corn, and it infects the interior of stems when severe. Beginning on the leaf sheath near the ground, watery spots appear grayish green, and gradually develop toward upper leaf sheaths, leaves and surroundings, and finally the disease department is dry. The lesions on the leaves and leaf sheaths are the same, both oval and round, expanding into moire. When the air is dry, the middle of the lesion is yellow and the edges are grayish brown; when the air is wet, there are many mycelia on the lesion. The hyphae gathered into a small white pompon and gradually turned into brown sclerotia.
Second, the main basis
I station staff in the survey from late May to early June in Shichuan, Longxing, Dawan, Luoyi, Dasheng, Tongjing and other towns survey, there are varying degrees of occurrence of sheath blight hazards. The strain rate was 2.5%-9.5% with an average of 3.8%. Compared with the same period of last year, the occurrence period was about 10 days late. It is estimated that about 86,000 mu of sheath blight has occurred in the region. According to meteorological data, the weather in the middle and late June is conducive to the occurrence and spread of corn sheath blight. It is expected that this year will be the year of overweight. Therefore, the leaders of towns and villages and agricultural technicians should strengthen publicity and pay close attention to urging farmers to prevent and cure as soon as possible.
Third, prevention and control measures
1. Remove diseased leaves, burn them in time, and immediately apply pesticides to prevent re-infection.
2, drug control. Apply 20% Jinggangmycin 100g water to 50kg spray per acre. Spray it once a week. Can also take the method of painting stalk, better control effect.
Note: To ensure the safety of humans and animals, the use of highly toxic and high residue pesticides is prohibited.

Medicine for came,including antibiotics, hormones, feed, vitamin nutrients, etc.
Veterinary drugs refer to substances (including drug feed additives) used for prevention, treatment, diagnosis of animal diseases or purposeful regulation of animal physiological functions.
Veterinary drugs can be roughly divided into four categories: â‘ general disease prevention and treatment drugs; â‘¡ Drugs for prevention and treatment of infectious diseases; â‘¢ Drugs for prevention and treatment of internal and external parasitic diseases; â‘£ (including growth promoting drugs). Except for the biochemical immune products (vaccine, vaccine, serum, antitoxin, toxoid, etc.) for the prevention and treatment of infectious diseases, as well as special veterinary drugs for livestock and poultry parasitic diseases and growth promoting drugs, the rest are the same as those for human use, but the dosage, dosage form and specifications are different. It has long been widely used in the prevention and control of livestock and poultry diseases.
More than 20 kinds of veterinary drugs are commonly used, such as analgin, amoxicillin, florfenicol, ceftiofur, oxytetracycline, chlortetracycline, bacitracin, salinomycin, monensin, colistin, etc. 60% of antibiotics were used in chemotherapy; 40% is used as feed, which can not only prevent infectious diseases, but also promote the growth of livestock and poultry and improve the utilization rate of feed.
Among the Antiparasitic Drugs, in addition to the common anti helminth drugs (mebendazole, levamisole, thiadiazine, etc.), anti schistosomiasis drugs (antimony agent, nithiocyandiamide, praziquantel, etc.) and anti tapeworm drugs (niclosamide, etc.), the special anti Fasciola hepatica drugs (nitrochlorophenol, trichlorobenzole, etc.), Trypanosoma, and pyroplasmosis drugs (antracel, suramin, chloramphenicol, etc.) for livestock and poultry are also used Imidacloprid and other insecticides (organophosphorus insecticides). A macrolide ANTIBIOTIC was found to have a significant killing effect on parasites such as gastrointestinal nematodes, Dermatophagoides, blood sucking lice, especially Sarcoptes scabiei. Coccidiosis is a serious threat to the safety of chickens and rabbits. There are more than 30 kinds of commonly used anticoccidial drugs, including synthetic drugs (such as chlorobenzoguanidine, changshanone) and antibiotics (such as monensin, salinomycin), which are often used alternately.
Biochemical immune products are mainly used to prevent animal anthrax, brucellosis, anthrax, salmonellosis, and a variety of viral infectious diseases.
Injections are commonly used in veterinary drug preparations, but their specifications are several times larger than those for human use. Oral veterinary drugs are usually in powder or microcapsule form, as feed additives, mixed into the feed for free feeding of livestock and poultry. Anabolic hormone can increase the benefit of raising livestock and poultry. It is mainly made into implant for subcutaneous implantation. Transdermal preparations and medicated baits for aquaculture are emerging.
