Over the years, the prolonged use of sulfonylurea herbicides by farmers has led to increasing weed resistance in wheat fields. As a result, traditional herbicides are becoming less effective, which now poses a serious threat to wheat production. To address this issue, we’ve gathered insights from recent experiences and would like to introduce a few safe and efficient herbicides that can help maintain optimal crop health.
The best time to control weeds in wheat fields is before winter, during the 3-leaf stage. At this point, applying herbicides ensures maximum effectiveness. For pre-winter weed control, you can use 36% Pentium WP at a rate of 5g per mu, or 5–10g in spring. Another effective option is 40% Fast Kill Ling (1+1) WP. This herbicide is known for its broad-spectrum activity, fast action, and ability to kill weeds thoroughly, even under adverse weather conditions. It performs well at low temperatures as low as 5°C, making it a reliable choice in early spring. One of its most notable advantages is its safety profile for wheat and sorghum crops.
When using herbicides in wheat fields, there are several important points to keep in mind:
1. Always use the secondary dilution method: first mix the herbicide into a concentrated solution, then add a small amount of clean water to the sprayer, pour in the concentrated solution, and finally top up with water to the desired volume.
2. Weather plays a crucial role in herbicide effectiveness. Try to spray on sunny, windless days to ensure better coverage and absorption.
3. Be cautious to avoid drift that could harm neighboring crops, as this may lead to phytotoxicity.
4. After application, make sure to clean the sprayer’s tank and nozzles promptly to prevent residue buildup and ensure future performance.
By following these guidelines and using the right products at the right time, farmers can effectively manage weeds and protect their wheat yields. With proper application techniques and careful selection of herbicides, it's possible to maintain productivity while reducing the risk of resistance development.
Anti-Viral
The virus is composed of a nucleic acid molecule (DNA or RNA) with a protein consisting of non-cell morphology of the campal life of the living body. The general symptoms of viral infection are fever, headache, cough and other symptoms of systemic poisoning and viral host and invasion of tissues and organs leading to inflammatory symptoms caused by local symptoms (diarrhea, rash, liver function damage, etc.). Different symptoms of the different virus, some viruses can also damage the myocardium, causing viral myocarditis. There are two types of viral infections, mostly recessive infections (subclinical infections), and a few are dominant infections. Dominant infection can be divided into acute infection and persistent infection. There are many ways of antiviral infection, such as direct inhibition or killing of viruses, interference with virus adsorption, prevent viruses from penetrating cells, inhibit viral biosynthesis, inhibit viral release or enhance host antivirus capabilities. At present, there are several major types of antiviral drugs: Anti-Respiratory virus infection drugs, anti-immune virus drugs, anti-hepatitis virus drugs, anti-herpes virus drugs.
