Carbamate insecticides

① plus Baofu: 3% good year winter granule, 40.6% good year winter water suspension powder, 75% good year winter wettable powder and so on. It has the function of stomach poison, contact poison and permeation and migration. After spreading, it can be absorbed and migrated into the plant by the root or leaf tissue of the plant to kill most of the pests. It is a widely effective insecticide, which is effective against aphids, shell insects, nematodes and other pests with strong toxicity. When using this insecticide, cultivation managers should be very careful and do a good job in the safety protection of pesticide application to avoid poisoning.

② butyl plus Baofu: 40% New year Dan wettable powder and 48.34% New year Dan emulsion. It has permeability and contact with poison, and is effective against piercing and sucking pests. However, stab-sucking pests, such as thrips, are extremely resistant to various chemical pesticides, and it is appropriate to use the same pesticide not more than four times in a row, so as to avoid being unable to kill thrips because of drug resistance, and continue to expand the harm. Affect the growth of the orchid.

③: 10% Wanqiang granule and 24% Ozone solution. It has osmotic migration, contact with poison, and has a control effect on nematodes. It can be used as a medium treatment agent. It is highly toxic and should be used carefully. When poisoned, please see a doctor as soon as possible. Atropine sulfate can be used to detoxify the antidote.

The application of pesticides is mainly to protect the roots, stems, leaves, flowers, growth points and other organs of Iris from the interference or invasion of diseases and insect pests, so that the orchid grows in a dominant environment and thrives day by day, which can not only grow into good quality and high yield, but also bring rich benefits to cultivation managers. However, it is located in tropical and subtropical areas, the climate is hot and humid, and the cultivation of orchid is restricted by laws and regulations, and the cultivation space is narrow, so the cultivation managers cultivate in intensive greenhouse in order to improve the return on investment. National orchid grows in this high-temperature, humid, intensive cultivation environment, diseases and insect pests are easy to breed and spread. In order to protect the growth of national orchid, cultivation managers strictly require its growth speed and quality, so the application of pesticides has become an indispensable important material for the cultivation of national orchid. The use of pesticides is the most economical, rapid and effective method for the control of diseases and insect pests.

However, for the use of pesticides, it is very important for cultivation managers to choose the types of pesticides. Only by correctly identifying the characteristics of diseases and insect pests and choosing the right pesticides can we prescribe the right medicine to achieve the effect of disease control. The inability to correctly judge the symptoms of diseases and insect pests or the improper use of pesticides will often bring many potential crises. It is believed that there are some cultivation managers in the national orchid community, because of the losses caused by the wrong use and the wrong selection of control objects. there are many reasons that can not achieve the control effect, such as wrong dilution times of pesticides, improper selection of pesticides for control objects, excessive absorption and accumulation of certain elements by plants, and so on. Therefore, cultivation managers usually carry out pest control, the selection and application of pesticides can not be ignored.

Due to the prevention and control of diseases and insect pests in the national orchid, so far, there is no dedicated organization to specialize in studying, publishing or compiling a complete map of diseases and insect pests and control methods, for the national orchid growers in pest control, according to the symptoms of diseases and insect pests and choose the right pesticides, to do the most safe and effective control, so as to prevent cultivation managers from working hard and wasting their painstaking efforts.

Here, the author suggests that the relevant associations of the national orchid should set up a pest control research center as a whole, and employ domestic well-known pest and pest scholars and experts to collect and detect the occurrence of diseases and insect pests specifically for pest control projects. and publish a national orchid correct pest and pest map and recommend the fully effective efficacy of prevention and control, to provide growers to solve the most important problems in management. Lest growers do not have complete and detailed reference materials because they are unable to judge symptoms and fail to understand the nature of pesticides, prevention and control objects, methods of use, and what will happen after use, resulting in growers often using things such as ineffectiveness or drug damage, resulting in serious losses. if there is no information on correct cultivation management, to cultivate a better sense of achievement and achievement. On the other hand, the cultivation managers are left to grope for themselves in cultivation, accumulate experience in failures again and again, waste a lot of financial resources, and consume a lot of money and time. In the case of large investment and no profit, the population of cultivation will be reduced, and the promotion goal of driving the cultivation of national orchid will also be affected.

Most of the pesticides used in pest control are chemical synthesis, the physiological characteristics of different varieties of orchids are different, the cultivation environment is different, and affected by the existence of various external factors, and the effect of pesticide use and tolerance to pesticides are also different. pesticide hazards are often hidden, such as the application of a large amount of organophosphorus pesticides, which often inhibit the growth of roots, stems, leaves and other parts.

Because of the shallow talent and knowledge, limited knowledge and little cultivation experience, the author can only provide reference to the pesticides that I have used in cultivating Guolan, while the application of pesticides is a specialized knowledge, which is beyond my ability in the field of professional theory. Before using the pesticide provided above, the cultivation manager should first consult the relevant government authorities and choose the low-priced Guolan, after a long-term single pesticide test. It is proved that it has significant efficacy and no drug damage or growth inhibition to the orchid before it can be used in a large area to avoid unnecessary loss. It is hoped that the elders of the orchid world can provide more techniques for the cultivation of the national orchid, so that the new cultivation managers have smooth cultivation information to create the national orchid industry and make it develop more vigorously.
