How to prevent peanut virus disease

Peanut virus disease is one of the major diseases of peanuts, which seriously affects the output and quality of peanuts. It is particularly serious in the production areas in northern China. Peanut virus disease, in addition to bud blight is mainly transmitted by the thrips, other diseases such as light mottle disease, yellow mosaic disease, common mosaic disease is transmitted through the seeds and mites, and the major primary infestation sources of these disease-borne diseases are transmitted. . The transmission rate is mainly affected by the onset period, early onset, and the rate of species transmission is high. The seed poisoning rate is negatively correlated with the seed size, the high seed rate is low, and the small seed rate is high. In the presence of toxic and susceptible species, the occurrence of locusts sooner or later and the number of viral diseases are the main factors. The locusts that transmit the virus are mainly winged crickets in the field. In the early stage of peanut, the locusts occur early and the quantity is large, which may cause serious disease epidemic, otherwise the incidence is light. The rainfall during the seedling stage of peanuts is mild, and the weather is mild and dry. This can easily lead to the occurrence of large scale locusts and cause disease epidemics, whereas it is lighter. Control methods: First, use non-toxic or low-toxic seeds to prevent or reduce the initial infestation source. Non-toxic seeds can be obtained by isolation and propagation. The second is to select varieties such as Yuhua No. 1, Haihua No. 1, and Yuhua No. 7 which are light and low in the rate of species propagation, and select large particles of kernels as seeds. The third is to promote the technology of plastic film covering. The plastic film has a certain effect of repelling fleas and can reduce the harm of virus diseases. The fourth is the timely removal of weeds in the field and surrounding areas, reducing the source of locusts. The fifth is to do a good job of disease quarantine, and it is forbidden to adjust seeds from the ward. Sixth, the drug is used for the treatment of lice. When sowing, 3% of carbofuran granules are used for seeding. The dosage per acre is 2.5 kg-3 kg. It can also be covered with 25% phytophos (812). The dosage per acre is 0.5 kg. After the emergence of peanuts, they should be promptly inspected and the aphid should be promptly sprayed with 40% dimethoate EC 800 times in order to prevent the aphid from transmitting the virus.

Consumer electronics refers to the audio and video products used by individuals and families in relation to radio and television. They mainly include: TV sets, DVD players, VCRs, camcorders, radios, tape recorders, , Record players, compact disc players (CDs) and more.

In some developed countries, however, telephones, personal computers, home office equipment, home electronic Health Care equipment, automotive electronics, etc. are also classified as consumer electronic products. With the advent of technology and new applications of new products, digital cameras, mobile phones, PDAs and other products are emerging as emerging consumer electronic products.

Since the late 1990s, information appliances integrating three fields of computer, information and communication, and Consumer Electronics have begun to penetrate into family life extensively. It has such functions as audio-visual, information processing and two-way network communication, Processor, associated supporting hardware (such as a graphics card, storage media, IC card or credit card reading device), embedded operating system and application layer software package. Broadly speaking, information appliances include all household appliances such as PCs, set-top boxes, HPC, DVDs, super VCDs, wireless data communication devices, video game devices, WEBTV, etc. that can exchange information through the network system. Currently, audio, video and communications equipment is a major component of information appliances.

In the long run, refrigerators, washing machines, microwave ovens and the like will also develop into information appliances and form an integral part of smart appliances.
