Citrus anthracnose is a latent enemy. As long as the tree is weak and the climate is suitable, it will erupt, and once it breaks out, even if rescue measures are taken immediately, the recovery of the tree will take one or two years. Therefore, strict implementation of the prevention and control measures for citrus anthracnose can prevent the extent of the problem.
Once anthrax has spread, immediate action must be taken to control the development of the epidemic. The fungicide control is the fastest and most effective, but what fungicide is used? Because so far, there is no bactericide specific drug for controlling anthrax. In dozens of domestic and foreign pesticide fungicides, the efficacy comparison test was carried out.
After measurement, the best bactericidal effect is prochloraz, followed by triazole pesticides such as difenoconazole.
Recommended formula 25% prochloraz cream 1000 times +80% Dasheng wettable powder 500 times
Prochloraz can quickly kill anthrax, and Dasheng is wearing a protective clothing like a tribute tree, which can inhibit the infection of bacteria in the body and resist the invasion of external bacteria. To achieve the purpose of controlling anthrax. It is important to treat the disease , but it is more important to prevent it.
To control citrus anthracnose, we mainly do the following aspects.
In the first place, we must promptly remove, diseased, diseased, and diseased fruits.
Second, it is necessary to increase the application of potassium fertilizer and organic fertilizer to improve the disease resistance of Gongganshu.
The third scientific pruning prevents the canopy from being covered. The fourth guarantees that the drainage system is unblocked and prevents water from accumulating in the orchard. The fifth timely harvest, let the tree restore the tree early.
Ordinary mullite porcelain is made of aluminosilicate natural minerals as a main raw material, and is formed by a reaction sintering method in which a eucalyptus is synthesized in a sintering process or a mullite is first synthesized and then sintered. Due to the low purity of raw materials and high impurity content, in addition to Al2O3 and SiO2, the components also contain impurities such as TiO2, Fe2O3, CaO, MgO, Na2O, K2O, etc., so that there are a considerable amount of glass phase in the product, resulting in mechanical and thermal properties. Poor, the excellent performance of mullite ceramics at high temperatures cannot be fully utilized. Therefore, ordinary mullite ceramics in the industry can only be used as a general refractory material in the case where the temperature and high temperature strength are not high.
