Description

Medicament for preventing and treating peanut root rot and preparation method and use method thereof
Technical Field
The invention relates to the technical field of crop planting, in particular to a medicament for preventing and treating peanut root rot, a preparation method and a use method thereof.
Background
In recent years, peanut root rot occurs in each peanut producing area in Guangdong province, and the condition is serious, so that the peanut root rot has great influence on the peanut yield, and the peanut yield is directly reduced. The peanut root rot is commonly called rotten root and is caused by the infection of fusarium in deuteromycotina, and comprises 5 strains of fusarium oxysporum, fusarium solani, fusarium pink, fusarium tridentatum and fusarium moniliforme, and can occur in each growth period of peanuts. The disease of the peanuts before emergence of seedlings after sowing can cause seed rot and bud rot. The seedlings are damaged, the main roots are browned, and the plants are withered. The long-strip brown disease spots appear on the roots and the roots of the damaged main roots in the adult plant period, the root ends are wet-rotten, the overground parts of the diseased plants are short and small, poor in growth, yellow in leaves, few in blossoms and fruits, and the whole plants are withered finally.
The incidence rule of peanut root rot is as follows: pathogenic bacteria mainly live through the winter in soil along with disease residues and become the main primary infection source of diseases, and the kernel and the pod with bacteria and the soil miscellaneous fertilizer mixed with the disease residues can also become the primary infection source of diseases. The isolation of the initial infection source of the root rot is important before sowing, and at present, the attack of the root rot is prevented and controlled by chemical means such as carbendazim, fludioxonil, pyraclostrobin, metiram and the like used in the conventional production of peanuts. This not only causes environmental pollution, but also seriously affects human health. As a novel botanical pesticide, the traditional Chinese medicine antibacterial agent becomes a new means for preventing and treating crop diseases by replacing a chemical method. Researches show that the honeysuckle, the katsumadai seed, the coptis chinensis, the radix sophorae flavescentis and other traditional Chinese medicinal materials have the effect of inhibiting fusarium in deuteromycotina and provide possibility for preparing a traditional Chinese medicinal antibacterial agent for preventing and treating peanut root rot.
In addition, when the bactericide is used for inhibiting the peanut from developing, the disease resistance of the peanut is enhanced, the growth and development of the peanut are promoted, the peanut can successfully pass through the high-risk period of developing the peanut, and the key point for preventing the root rot is also provided. Iron is an indispensable trace element of plants, is a component of various oxidases, ferredoxins and nitrogenase in plants, participates in the redox reaction in the plants, promotes the normal operation of nitrogen metabolism, and enhances the disease resistance of the plants. Zinc is a nutrient element necessary for the growth and development of plants, is a composition of various enzymes in plants, and influences metabolic processes such as carbon dioxide photosynthetic reaction and the like. Can promote synthesis of auxin, carbohydrate conversion and protein synthesis. The zinc can promote the absorption of nutrient elements such as nitrogen, phosphorus, potassium and the like by the peanuts, so that the peanut plants are robust and grow vigorously. Copper can promote the growth and development of plants, improve the photosynthesis strength of the plants, promote flower bud differentiation, improve the cold resistance, drought resistance and disease resistance of the plants and improve the stress resistance of the plants. Most of the current peanut production only uses a single antibacterial agent, and omits the combination of various trace elements for seed dressing, thereby prolonging the high-risk period of the root rot disease of the peanuts.
Therefore, the search for a safe novel medicament for preventing and treating the rooting rot of the flowers becomes a current urgent priority for peanut production.

As can be seen from the table above, the incidence of root rot is greatly reduced after the treatment of the medicament prepared by the invention, and the medicament has outstanding control effect on the root rot, thereby greatly improving the yield of peanuts.
Control test alone
1. Summary of the test: the test was conducted in 2016 in a test field in the cloud base of Guangdong institute of agricultural sciences, Guangdong, 3 months.
2. Test materials: peanut seeds Yue oil No. 13, air flower No. 2 and Yue oil 390, and the color-changing, rotten and damaged seeds are removed, namely the medicament prepared in example 2.
3. The test process comprises the following steps:
(1) respectively placing peanut seeds Yue oil No. 13, flos Farfarae No. 2 and Yue oil 390 into 3 clean plastic pots, and soaking with traditional Chinese medicine antibacterial component A at room temperature for 2 hours (control 2 and blank control groups are not treated at all);
(2) directly spraying the trace element nutrient solution components on the three peanut seeds by using a sprayer while stirring until the seeds are wet, and directly sowing without waiting for the seeds to be dried (the control 1 and the blank control are not treated);
(3) random block arrangement is adopted, dibbling is carried out, the plant row spacing is 10cm multiplied by 25cm, 25 holes are arranged in each cell, and the operation is repeated for two times;
(4) after the emergence of the peanut, the Chinese medicinal antibacterial component B was sown on soil and watered (control 2 and blank control were not treated at all).
(5) Other field management measures are equal to those of a common peanut field;
(6) in a full fruit and mature period, adopting a random five-point sampling method, taking 10 peanuts, investigating the occurrence condition of root rot of the peanuts in the field, counting the number of diseased plants, and calculating the disease incidence (the number of diseased plants/the investigation total number of plants multiplied by 100) and the prevention and treatment effect [ (the number of diseased plants at one point of the number of diseased plants per the comparison number of diseased plants multiplied by 100 ];
(7) and calculating the yield increasing rate of the peanuts treated by the medicament.

As can be seen from the above table, the common treatment of the traditional Chinese medicine antibacterial component and the trace element nutrient solution component can greatly reduce the incidence rate of root rot and improve the control effect of the root rot, meanwhile, the yield of peanuts is increased, and the common treatment effect is much better than that of any single group. Therefore, the traditional Chinese medicine antibacterial component and the trace element nutrient solution component of the application generate a synergistic effect on the prevention and treatment of the flower root rot.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
