Potato Late Blight (Potato Late Blight) is a devastating oomycete disease caused by phytophthora infestans that results in death of Potato stems and leaves and rot of tubers. When the leaves are infected, green brown spots are soaked in water at the leaf tips or leaf margins, the peripheries of the infected spots are provided with light green halos, the infected spots are rapidly enlarged and brown when the humidity is high, a circle of white mould, namely cyst stalks and sporangia, is most obvious particularly on the leaf backs, the infected spots become brown and dry when being dried, are crisp and easy to crack, do not see white mould, and have slow expansion speed, and brown streak spots appear when the stems or leaf stalks are infected; the seriously ill leaves can wither and contract, so that the whole plant is black and rotten, even one scorched field emits putrefactive odor; the tubers are infected by brown or purple brown large disease spots, are slightly sunken, and the subcutaneous potato flesh at the diseased part is brown and slowly expands or is rotten all around.
The pathogenic bacteria of the potato late blight mainly live through the winter in potato blocks by mycelium, and the potato blocks with the pathogenic bacteria are sown, so that the potato blocks do not germinate or die after germination and unearthed, some unearthed potato blocks become central diseased plants, and sporangiums generated in diseased parts are re-infected by airflow propagation to form a diseased center, so that the disease is spread and expanded rapidly from point to surface; the sporangia on the diseased leaves can infiltrate into soil along with rainwater or irrigation water to infect potato blocks to form diseased potatoes, and the diseased potatoes become a main infection source in the next year. Therefore, the potato late blight has great harm to the planting of the potatoes.
The method for preventing and treating potato late blight in the prior art mainly comprises the following steps: 1. selecting disease-free seed potatoes to reduce initial infection sources, strictly removing the disease potatoes each time in the processes of autumn harvest and cellar entry, winter storage and cellar checking, cellar exit, dicing, vernalization and the like, conditionally establishing a disease-free seed reserving land and performing disease-free seed reserving; 2. the cultivation management is enhanced, the seedlings are sowed early in a proper period, the field with loose soil and good drainage is selected for planting, the field humidity is reduced, the robust growth of plants is promoted, and the disease resistance is enhanced; 3. crop rotation and stubble replacement are performed to prevent continuous cropping and continuous cropping with solanaceae crops or close to planting, crop rotation with cruciferous vegetables is performed for more than 3 years, and adjacent planting with potatoes is avoided; 4. strengthening field management, applying enough base fertilizer, applying formula fertilizer, avoiding applying nitrogen fertilizer partially, applying phosphorus and potassium fertilizers additionally, preventing and removing weeds in time after field planting, reasonably training branches, pinching and branching according to the fruiting habits of different varieties, reducing nutrient consumption and promoting the growth of main stems; 5. reasonable close planting, wherein different close planting modes are adopted according to the growth period and fruiting habit of different varieties, so that the ventilation and light transmission conditions in the field can be improved, the field humidity is reduced, and the occurrence of diseases is reduced; 6. sterilizing the potato seeds, and optionally sterilizing with proper disinfectant; 7. in the early disease stage, proper medicament can be selected for controlling the disease in the early disease stage of the plant. In the control method, the seeds are correspondingly subjected to bacteriostatic treatment in the early planting stage, so that the control method has a remarkable effect on controlling the potato late blight, and the development of the method for efficiently controlling the potato late blight has important significance on potato planting.
