The disease mainly damages leaf sheaths, stems and leaves. The leaf sheath became infected and a dark green, irregular water-stained spot appeared at the base of the leaf sheath. Afterwards, it spread to the entire leaf sheath. After the diseased part was dry, it was gray and white and was a short black spot. The stem was infected. The water-stained, prismatic or elliptical to irregular dark green shuttle-like lesions appeared at the beginning. The lesions were dark yellow with water stains. The diseased tissue became soft and sags. Black dots or short-line spots appeared on the lesions. Sometimes arranged in concentric circles. With the development of the disease, lesions at the stem gradually expand upward into strips of yellow and large, resulting in dry and yellow phyllosma, and a large number of mild gray mold layer. In severe cases, until the death of the whole stem, the lower part of the lesion The pole remains green. The pathogenic bacteria mainly overwintered the mycelium on the soil disease and the new production area took the germinated bulb as the initial infestation source. Spores were transmitted by rainwater and irrigation water, and the rainwater was frequent, and the rainfall was easy to be affected. In addition, the terrain was low and the lines were closed early, with poor ventilation and light transmission, partial application of nitrogen fertilizer, growing overly prosperous, and the incidence of soft stems was heavy. In the field where stem blight occurs, early onset, timely foliar spraying, available 25% carbendazim WP 250 times or 50% thiophanate-methyl WP 800 times; 7-10 days , continuous 3-4 times, to control the spread of the disease. In addition, rational fertilization, increased phosphorus and potassium fertilizers and farmyard fertilizers, especially silicon-containing phosphate fertilizers, ensure adequate nutrients, improve physiological metabolism, increase seedling epidermis siliceous thickness, and enhance plant disease resistance. Veterinary Drug Preparation For Poultry
Medicine for poultry.
Medicine for cattle,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. germicides in breeding period,fungicides at rest,Quick acting bacteriostatic agent,slow acting antimicrobial agents Shandong Unovet Pharmaceutical Co.,Ltd. , https://www.unovetcn.com
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.
Frequent rain causes re-emergence of mast blight
This is one of the important economic crops in our county. The annual planting area is more than 500 mu. In recent days, barb disease has occurred in some field plots, yellowing of stems and leaves, and death and other symptoms have occurred. This not only results in a reduction in yield but also a significant impact on quality. The disease occurrence and control techniques are briefly described as follows:
