Normal pre-winter use of tribenuron-methyl has little effect on succeeding cotton
Liu Wenzhang from Hengjing Town, Gaoyou City called to say that he sprayed tribenuron-methyl in his wheat field for chemical weed control, using the product according to the instructions, with the per-mu rate of 10% tribenuron-methyl at less than 15 grams. He heard that tribenuron-methyl, chlorsulfuron and metsulfuron-methyl belong to the same class of herbicides, and that chlorsulfuron and metsulfuron-methyl both have very long residual activity periods, often causing residual phytotoxicity to succeeding crops. He did not know how long the residual period of tribenuron-methyl is, and whether a field sprayed with tribenuron-methyl before winter would suffer from herbicide residue effects when cotton is planted as the succeeding crop. Tribenuron-methyl is a commonly used herbicide for controlling broadleaf weeds in wheat fields. Wheat, large

Detailed Explanation of Lincosamide Antibiotics Commonly Used in Geese
Source and properties: This product is extracted from the culture broth of a Streptomyces variant. It is a white crystalline powder, alkaline, bitter in taste, and soluble in water. Its hydrochloride salt is easily soluble in water. Both the aqueous solution and the dry product are relatively stable. Actions and uses: The antibacterial action of this product is similar to that of erythromycin, but its antibacterial spectrum is narrower than that of erythromycin. It has strong antibacterial action against most Gram-positive bacteria such as Staphylococcus aureus, Streptococcus, Clostridium welchii, etc., and also has a significant effect on mycoplasma. Clinically, it is mainly used to treat mycoplasmosis, necrotic enteritis, staphylococcosis

Pig poisoning is mostly caused by feeding them half-cooked feed
Some farmers feed pigs with half-cooked feed, and shortly after eating, the pigs become restless and agitated, walk unsteadily, have difficulty breathing, and die from convulsions. This is food poisoning, and the main causes are as follows: First, putting green vegetables in a pot and cooking them slowly over low heat for a long time without stirring them can easily produce a toxic substance called hydrocyanic acid, and pigs are highly susceptible to poisoning after eating it. Second, the feed is not cooked thoroughly and spoils after being left standing for a long time. When pig feed is kept sealed in a pot overnight at around 40°C to 70°C, the nitrates in the feed will turn into a toxic substance called nitrite

A detailed explanation of the guidelines for the use of pollution-free fishery drugs: scientific medication is safer
Although fishery drugs can treat diseases of the farmed fish, shrimp and crabs, because aquatic products will ultimately be placed on people's dining tables, attention must be paid to the safety of the drugs used to prevent and treat their diseases. To prevent harmful substances contained in aquatic products from harming human health, the Food Hygiene Law stipulates that aquatic products such as fish, shrimp and crabs must not contain antibiotics or synthetic antibacterial agents or other substances harmful to human health. To prevent drug residues, it is necessary to understand the correct methods of drug use and the withdrawal period. The relevant national authorities have issued the "Pollution-Free Food

Can onion skin soak be used to make fertilizer
A solution made by soaking onion skins not only contains a substance that can kill pathogenic microorganisms in the soil, but also contains a variety of trace elements, so it can be used as fertilizer for crops. 1. When growing flowers indoors, if onion skin soak is used as fertilizer, the flower branches grow luxuriantly and the flowers are more vivid. 2. Yellowing cucumber seedlings are especially suitable for spraying with onion skin soak; after spraying, the vines turn from yellow to green, grow vigorously, and soon bloom and bear fruit. Method for making onion skin soak: use 100 g of onion skins, add 25 g of hot

How to prevent and control gummosis in greenhouse apricots? A detailed practical guide
Apricot gummosis is a typical physiological disease caused by many factors, such as hail injury, insect injury, frost injury, sunscald, mechanical wounds, etc. It is often easily triggered during top grafting for variety change or large branch renewal, and heavy summer pruning, improper fertilization, heavy clay soil, excessive acidity, improper pesticide use and the resulting phytotoxicity can all induce gummosis. Only by understanding the disease's occurrence pattern can effective prevention and control be achieved. The symptoms, occurrence pattern and control techniques are described below: Symptoms Gummosis mainly occurs on

Detailed explanation of year-round production technology for multiple mushroom species in one greenhouse
In 2001, our county began large-scale promotion of white beech mushroom (Pleurotus nebrodensis) production technology throughout the county. The white beech mushroom belongs to the medium-low temperature type of edible fungi, fruiting within the range of 5-20°C. Before fruiting, the white beech mushroom must undergo a low-temperature stimulation process, which determines that the fruiting period in our county is from late November to late March of the following year, causing the mushroom greenhouse to sit idle from April to November around summer, and the biological conversion rate of the white beech mushroom is also relatively low. Starting from 2002, our county began trial

What is yellow fat disease in pigs? A detailed explanation of causes, diagnosis, and prevention and control methods
1. The concept of yellow fat disease in pigs.

In pork whose subcutaneous fat turns yellow after slaughter, if it is caused by feed it is called "yellow fat pork," and if it is caused by disease it is called "jaundice pork." 2. Causes of yellow fat disease in pigs. There are mainly 2 causes that induce yellow fat disease in pigs: one is pathological, called jaundice, which includes parenchymal jaundice, obstructive jaundice

What causes gout in chickens? A comprehensive analysis of the causes
Gout is a metabolic disease caused by a disturbance in uric acid metabolism in the chicken's body, in which the uric acid concentration in the blood rises, large amounts of uric acid are excreted through the kidneys; kidney damage and reduced kidney function caused by various factors further obstruct uric acid excretion, resulting in uric acid poisoning. It occurs mostly in broiler chickens and caged chickens. The main causes of gout in chickens are as follows: 1. VA deficiency. VA has the function of protecting mucous membranes; when deficient, it can cause keratinization and squamous epithelial metaplasia of the renal tubules, collecting ducts and ureters. Due to the epithelium
