First, choose different herbicides according to different soil characteristics, microbial species, climate and irrigation conditions. Herbicides containing chlorsulfuron-containing components are mainly degraded in the soil by hydrolysis. When Daejeon encounters alkaline soil, low rainfall in the year, and soil drought, their residual period in the soil tends to be prolonged, and crops are susceptible to flooding. On the other hand, when acid soils, soils are wet or irrigation farmland, the residual period is shortened. After the crop is relatively safe. 2. Before planting crops after planting, it should be known whether the herbicides applied to the former crop have phytotoxicity on the crops of the rear crop. For example, if herbicides containing chlorsulfuron-methyl, metsulfuron-methyl, such as wheat straw, wheat straw, etc. are used before, then crops such as corn, soybeans, cotton, peanuts, etc. cannot be cultivated, nor can they be used for paddy fields. In recent years, the use of tribenuron (also known as superstar, broad-leaf net) in some places has produced different degrees of phytotoxicity on the mandible peanuts, resulting in difficulties in seedling emergence, slow growth, and reduced yield. Third, improve the application methods to reduce the amount of soil residues. The first is that the amount of medicine to be used is accurate, the spray should be uniform, no leakage, no heavy spray. If herbicides containing chlorsulfuron-methyl components are applied year after year, they will not only cause phytotoxicity to crops but also have phytotoxicity to crops of the current season. The second is the flexible use period. It can be applied before the crop is sown, before the seedlings, or after the seedlings. At present, Pust, Guangmiaoling and Atrazine should use early post-emergence spraying to achieve the purpose of reducing the dosage and reducing the residue. When used after emergence, add additives or synergists to improve efficacy and reduce the amount of medication. The last is rational application of pesticides. The combination of chlorsulfuron and 2,4-D butyl ester can reduce the dosage of chlorsulfuron by 50%. Pussite soil treatment can be mixed with trifluralin, acetochlor, alachlor, saxin and others. Stripe spraying with Pusit and Guangmianling can reduce the dosage by more than 30%. Monkeypox is a viral zoonosis (a virus transmitted tothose seen in the past in smallpox patients, typically-presents clinically with fever, rash and swollen lymphnodes and may lead to a range of medical complications.It is caused by the monkeypox virus which belongs totheorthopoxvirus genus of the Poxviridae family.Thereare two clades of monkeypox virus:the West Africanclade and the Congo Basin (Central African) clade.Theoname monkeypoxoriginates from the initial discovery ofthe virus in monkeys in a Danish laboratory in 1958.Thefirst human case was identified in a child in the Demo-cratic Republic of the Congo in 1970.

How Herbicide Spraying Does Not Affect Later Crops
The use of certain herbicides remaining in the soil after being used for more than one year can easily result in different degrees of phytotoxicity to sensitive postharvest crops. For example, herbicides based on metsulfuron, chlorsulfuron-methyl, and ethametsulfuron, which are currently used throughout the country, can easily cause phytotoxicity, such as yellowing and dwarfing, in the growth stage of late-season rice. avoid.
