How to effectively treat viral disease in bell peppers?
Viral diseases are mainly spread when insects or friction wounds infect the plant with the virus. Control measures. (1) Do a good job of pest control: you can use imidacloprid, Yibianjing, Actara and other pesticides for foliar spraying, spraying once every 7-10 days to prevent the spread of viral disease. At the same time, install insect-proof nets at the vents to reduce pest damage. (2) Spray nutrient solution: you can spray the leaves with Fengshou No. 1 at 800 times mixed with 0.1% zinc sulfate (1 liang to 3 sprayers) for spraying, spraying once about every 7 days, which can effectively prevent viral disease

How to treat pear tree top rot? Silicon-calcium-magnesium fertilizer has good control effect
Pear top rot, also known as pear stem rot and pear iron-head disease, generally occurs on European pear varieties, so it is also called European pear top rot. The causative factor of pear top rot is currently unclear and is generally considered a physiological disease. In order to seek effective control methods, we conducted a control experiment using silicon-calcium-magnesium fertilizer and achieved good results. The experimental results are summarized as follows. (1) Experiment and methods: (1) Experimental materials. The experiment was set up in a pear orchard in Xishanbeitou Village, Dayao Town, Muping District, Yantai, Shandong, with the variety Bartlett pear

Cooling pigs in summer can effectively increase weight gain
Many farmers believe that "pigs do not grow in June," and that feeding them well or poorly makes no difference, so they relax feeding management in summer. In fact, as long as the following cooling measures are taken when raising pigs in summer, the pigs will not only gain meat but also grow just as fast. (1) Spray water on the pigs' bodies and the floor of the pig house to cool them down. When spraying water to bathe the pigs, do not spray their heads. (2) Supply cool clean water in a timely manner. After the pigs finish eating, give them enough clean cold water to drink. (3) Feed more green fodder. Feed an appropriate amount of high-energy feed. (4) Take mosquito prevention measures so the pigs can sleep quietly.

Detailed Explanation of Common Pond-Clearing Drugs and Their Effects
Drug-based pond clearing is the use of drugs to kill various predatory fish, wild trash fish and other harmful organisms in the pond that endanger fish, shrimp and crab fry, creating a safe environmental condition for fry rearing. This is an important measure for improving the survival rate of fish, shrimp and crab fry. The commonly used pond-clearing drugs and their effects are introduced as follows: 1. Quicklime pond clearing and its effects: The action of quicklime in pond clearing is that after quicklime meets water, a chemical reaction occurs, producing calcium hydroxide and releasing a large amount of heat. Calcium hydroxide is a strong base, and its hydroxide ions can raise the pH value of the pond water to above 11 in a short time, thereby killing wild trash fish and other harmful organisms.

Effective prevention and treatment methods for false pregnancy in sows
What is false pregnancy? After mating, a sow is not actually pregnant, but her belly grows day by day, and her udder gradually enlarges, until in the end some clear milk can even be squeezed out, yet she does not give birth; then the belly and udder gradually shrink back. This phenomenon is called false pregnancy. Causes of false pregnancy: First, due to early embryonic death and absorption, the corpus luteum of pregnancy does not disappear, causing progesterone to continue being secreted, as if the pregnancy were still continuing. Second, due to malnutrition, the sow's endocrine system becomes disordered, and the sow's estrous cycle is delayed

A Brief Introduction to the Effect of Mannich Base Ingredient in Killing Fish Parasites
Mannich base ingredient is a highly efficient biological insecticide extracted from the roots and leaves of the pure plant eucalyptus and made through scientific processing. More than 1000 years ago, people already knew that eucalyptus has medicinal value. Especially in rural areas of southwest China, its roots and leaves are commonly soaked into a liquid to directly kill maggots and other pests. In recent years, after in-depth research by relevant departments at home and abroad, preparations have been extracted from it, and it is recognized as a biological insecticide that is broad-spectrum, highly efficient, low-toxicity, easily degradable, residue-free, free of "three-causing" effects, and

How Can the Disease Resistance of Fish Be Improved? 6 Effective Methods
Under current farming conditions, it is impossible to eliminate all pathogens. But to control the occurrence of fish diseases, we can start with scientific breeding management and maintaining the ecological balance of the aquaculture water body to improve the disease resistance of fish. As long as the measures are appropriate, we will achieve twice the result with half the effort. 1. Reasonable mixed culture. Reasonable mixed culture can not only increase the yield per unit area, but also has a certain effect on the prevention of fish diseases. Because the parasites suitable for different species of fish are not exactly the same, some parasites can only parasitize a certain species of fish,

Feeding chicks garlic sugar water can effectively prevent diseases
In the hot summer, chicks have relatively poor tolerance, so the probability of digestive tract and other diseases is relatively high. Today we introduce a disease prevention tip to prevent and treat chick colds, digestive tract diseases, selenium deficiency and other conditions. The specific method is as follows: take 50 grams of purple-skinned garlic or garlic, peel and mash into a paste, add 2 kg of warm boiled water, soak for 8 hours, then add 2 kg of prepared 10% sugar water, stir evenly, and feed to the chicks. When feeding adult chickens, an appropriate amount of iodized salt can be added to achieve the effect of disease prevention and treatment.

How to prevent and control contaminants in oyster mushroom cultivation? Covering with burnt mud ash is effective
Bed-style cultivation of oyster mushrooms: When bed-style cultivating oyster mushrooms, if contaminants appear sporadically on the surface of the substrate, they can be eliminated by smearing or covering the affected spots with thick quicklime slurry; if contaminants appear in large amounts on the substrate surface, cover the contaminated part with 2-3 cm thick burnt mud ash, making the covered area larger than the contaminated area, and pat it slightly firm to eliminate the contaminants; if contaminant contamination on the substrate surface is severe, cover the entire substrate surface with burnt mud ash and pat it firm, and after a few days the mycelium will resume normal growth. Bag-cultivated oyster mushrooms: first pick out the bags contaminated by unwanted organisms, then in a place with relatively high
