In recent years, tomato TY virus has been seriously affected, causing damage and loss to many tomato producing areas. In the production, the use of disease-resistant varieties has achieved good results, as long as the anti-TY varieties, most of the disease is mild or non-pathogenic, to solve the difficulties in production. However, after all, there are too few things that are perfect, and when applying disease-resistant varieties, some problems still need to be noted.
First of all, it should be noted that disease-resistant varieties are developed for disease resistance, and high yield, quality, flavor, shelf performance, etc. are not necessarily all excellent, and there may be a gap compared to the susceptible varieties being applied. Most of the disease-resistant varieties are difficult to reach the level of popularized varieties. Therefore, while their disease resistance is good, they should pay full attention to their weaknesses, and they must be selected from the disease-resistant varieties and have their main economic traits perform well. It is also necessary to fully understand the law of “no two good†varieties. Do not set the expected value too high. Perfect disease-resistant varieties do not exist, and good disease resistance is very good.
Second, it should be understood that disease-resistant varieties do not indicate that these varieties must be virus-free. During the cultivation process, TY virus can spread to these disease-resistant varieties if it is in the "infected area" of the disease, but because it has disease resistance, it does not show symptoms or symptoms are not easy to be found. . It can be seen that the plants of these resistant varieties may also be carriers of the virus. Bemisia tabaci can spread its virus out of the body. Therefore, when these disease-resistant varieties are cultivated, it is necessary to prevent the transmission of TY virus and kill the whitefly on the plants.
CPE is the sub-data of saturation high grade (FEN), the appearance is white powder, non-toxic and odorless, with excellent weather resistance, ozone resistance, chemical resistance and aging resistance function, with excellent oil resistance, flame retardant and coloring function. Excellent toughness (still flexible at -30℃), excellent compatibility with other polymer materials, high differentiation temperature, differentiation to produce HCl, HCl can catalysis CPE dechlorination reaction.
