At present, there are many types of pesticides produced by pesticide companies in China, of which pesticide formulations have developed rapidly and account for most of them. In 2006, the Ministry of Agriculture approved a total of 2,238 agricultural pesticide product registrations (excluding packaging-registered products), of which 218 were officially registered and 2020 were temporarily registered.
The reasons for the rapid development of pesticide mixtures in China are mainly the following: 1. Entering the 1980s, the emergence of drug resistance has caused people's great attention, with the help of North American and other countries, the successful precedent of pesticide mixed and mixed research, to give The old breeds are looking for ways to extend the life of newly synthesized pesticides, and the research of blends has begun. 2. Pesticide blending is one of the principles used in the scientific use of pesticides. A reasonable blending can expand the control spectrum, increase the effectiveness of control, reduce the cost of prevention and control, and delay or reduce the occurrence and development of drug resistance. 3. For those engaged in pesticide research, it takes only 1 to 2 years from the formulation screening of the mixture to the field trials. The cost is low and the benefits are significant. The results can be achieved quickly. 4. The development of new pesticides requires a lot of money and it takes a long time. For China's pesticide production companies, many SMEs do not have the ability to develop new pesticides. However, the production of mixed agent has the characteristics of simple process, low investment and quick effect, and can quickly obtain economic benefits, which is in line with the actual situation in China. 5. The use of mixtures can reduce the number of pesticides used, reduce the amount of use in the field, thus reducing the residual in crops and the environment, and help to protect the ecological environment.
Research status of pesticide mixtures in China:
1. Status of Insecticide Mixture: At the end of the last century, the total amount of pesticide mixture in China accounted for 57.01% of the mixture of pesticides, sterilization mixture, herbicide mixture, insecticidal mixture of sterilization was 18.15%, 41.1%, 9.79%. The proportion of insecticidal mixtures was reduced, the proportion of bactericidal mixtures was similar, and the percentage of herbicidal mixtures increased significantly. This shows that: first, the problem of resistance to herbicide mixtures is increasingly attracting people’s attention; second, simultaneous treatment of diseases, pests, and weeds. The function of reducing the number of medications and improving the efficacy of control has been valued by people. In the 1990s, the mixture of pesticides was mainly concentrated on the mixture of pyrethroids and organic phosphorus, organic phosphorus, and carbamates and organic phosphorus. The insecticidal mixture involved more than 90 single agents, including 28 organic phosphorus, 12 pyrethroids, and 9 carbamates. However, this situation has undergone great changes. In 2006, among the mixed products, the five most mixed combinations were:
1, abamectin + beta-cypermethrin, chlorpyrifos + triazophos, chlorpyrifos + beta-cypermethrin, triazophos + phoxim, avermectin + chlorpyrifos, and more focused on the sub-compounds, only avermectin The number of formulated dosage forms has reached 1084. Others include Meth salt, cyhalothrin, and acetamiprid.
2. Current status of bactericidal mixtures: Research on bactericidal agents is mainly focused on: (1) Selecting a mix of strong systemic bactericides and non-pigmented bactericides to achieve the purpose of delaying and overcoming resistance; (2) high costs The systemic fungicide is mixed with the low-cost protection fungicide to reduce the cost; (3) The different fungicides used for the target are mixed to make up for the deficiency that a single preparation can not simultaneously cure a variety of diseases.
3. Current status of herbicide mixtures: Herbicides are rapidly growing. Herbicides are used in combination to broaden herbicide spectrum, extend application duration, increase selection, and increase crop safety, while selecting two different effects. The herbicides of the mechanism are also effective and practical governance strategies to combat weed resistance.
2. Flexibility Training: Resistance bands can also be used for stretching and improving flexibility. They allow you to perform stretches safely and effectively, without putting too much strain on your joints.
3. Rehabilitation: Resistance bands are often used in physical therapy to help patients recover from injuries or surgeries. They can be used to perform low-impact exercises that help improve range of motion, flexibility, and strength.
4. Sports Training: Gymnastics resistance bands can also be used for sports-specific training. For example, they can be used to improve the strength and flexibility of a tennis player`s arm for better serves or a basketball player`s leg muscles for better jumps.
