Description
Technical Field
The invention relates to the technical field of pest control, in particular to a method for controlling soft rot of konjak by using chlorobromoisocyanuric acid.
Background
Konjak, also known as konnyaku, yunnao, Tou, Spanish Maranta, etc., belongs to herb plants of Araceae family, and is mainly distributed in Yun, Gui, Chuan, southern Shaanxi and western Hubei of China. The konjak contains rich konjak glucomannan, multiple vitamins and mineral elements such as potassium, phosphorus, selenium and the like; glucomannan has unique physicochemical properties and medicinal value, and can be used for preventing hyperlipidemia, hypercholesterolemia, diabetes, obesity, constipation, etc.; has wide application value in food and food additives; has good development prospect in the fields of cosmetics, edible films, chemical engineering and the like.
The soft rot of konjak is a difficult problem restricting the development of konjak planting industry at present. The soft rot of konjak is a bacterial disease which has great infectivity and destruction to konjak plants, is called as 'cancer' of konjak, is a plant disease caused by erwinia carotovora and can cause the tissues or organs of the plants to rot. The germs are weak parasitic germs, are mainly succulent and thick organs of harmful plants, such as tuberous roots, tubers, fruits, stem bases and the like, and are not limited to the fields, and also occur in the transportation process and the storage period. The soft rot of konjak can be transmitted by insect pest, soil, seed source and other ways. At present, the prevention and the treatment of the soft rot of the konjak mainly depend on the application of chemical agents, the chemical agents have high cost and are difficult to degrade, the chemical agents have damage or toxicity to plants, the problems of environmental pollution, pollution of konjak agricultural products and the like can be caused, and the quality and the export of the konjak products are greatly influenced.
The chlorobromoisocyanuric acid, also known as Deminxin bactericide king, Xiaojunling, Junduqing, Bixiudan and the like, can slowly release hypobromous acid and hypochlorous acid when being sprayed on the surfaces of crops, has four times of activity of the hypobromous acid, and has strong capability of killing bacteria and fungi. The compound is sprayed on crops, and the parent body after the hypobromous acid is released through systemic conduction forms the triazine diketone and the triazine, so that the compound has a strong virucidal effect; in addition, the starting material is rich in potassium salt and trace elements, so that chlorobromoisocyanuric acid has strong capability of preventing and killing bacteria, fungi and viruses. Chlorobromoisocyanuric acid is a low-toxicity bactericide and is widely used for the house control of plant diseases.
In the literature, "research on effects of different agents on prevention and treatment of soft rot of konjak" (modern agricultural science and technology, 2015), the effects of 72% agricultural streptomycin wettable powder, 20% thiediazole copper wettable powder, 77% fluazinam wettable powder, 50% chlorobromoisocyanuric acid (Jinxiakang) soluble powder, 20% bismerthiazol and other agents on prevention and treatment of soft rot of konjak are researched, and the research results show that: the seed soaking of the taro by using 1000 million U of 72 percent agricultural streptomycin wettable powder before the seeding of the konjac has better prevention effect on soft rot, the prevention effect reaches 46.16 percent, and the taro has obvious promotion effect on the seedling emergence, the plant height, the leaf disc diameter and the like of the konjac, and is obviously increased by 38.98 percent compared with a contrast; the prevention and treatment effect on the soft rot of the konjak can reach over 86.20 percent by continuously spraying 1000 times of 50 percent chlorobromoisocyanuric acid wettable powder and 500 times of 20 percent bismerthiazol for 2 times in the disease initial period, and the yield increase effect can reach over 28.64 percent.
Although chlorobromoisocyanuric acid has low toxicity and high degradation speed, the chlorobromoisocyanuric acid still has slight influence on the quality of crops when being frequently applied; moreover, the konjak has thin skin and strong absorption capacity, and the components in the medicament can easily enter the konjak. In addition, after the chlorobromoisocyanuric acid is applied, the microbial quantity in the soil can be reduced and the activity of enzymes in the soil can be inhibited within a period of time, so that the growth of the konjak is influenced.
