The cause and harm of strawberry anthracnose: high temperature and frequent rainfall, strawberry is extremely prone to anthracnose; if not timely control, it will reduce strawberry reproduction and strawberry seedling quality, serious will cause a large number of dead seedlings, or even no strawberry seedlings. Strawberry seedlings infected with anthracnose are used for production, and they are also prone to different degrees of death in a period of time after planting, and seriously need to destroy all the seeds. Therefore, the prevention and control of anthracnose should be started in the strawberry seedling stage. Prevention and control methods of strawberry anthracnose: first, heavy and moderate rain is easy to cause seedling land flooding, so it is necessary to dig ditches and drainage in advance to ensure that the water is dissatisfied with the border surface, the seedling bed does not accumulate water, and the ditch is dry after the rain. Second, timely watering is conducive to reducing ground temperature and replenishing plant water. Watering should be carried out in the morning and evening, drip irrigation is appropriate, and flood irrigation and hot days should be avoided. Reasonable topdressing, nitrogen fertilizer should not be excessive, increase the application of organic fertilizer and phosphorus and potassium fertilizer, cultivate strong plants and improve plant disease resistance. Third, for the seedling land with soil consolidation, it is appropriate to loosen the soil gently with a short-handle double-toothed hoe, and to compact the floating seedlings with soil to promote root development; the weeds in the seedling field should be pulled out manually in time to enhance ventilation and light penetration. Fourth, arrange the plants reasonably, remove the old withered leaves and the leaves and stolons infected with anthracnose in time, and take them to the seedlings for deep burial or burning treatment. Reasonable control of seedling density, when the density is high, it is appropriate to cut off the stolon of the mother plant and pull out the mother plant in time. 5. Strawberry seedlings can be covered with plastic film to protect themselves from rain to reduce humidity and cover sunshade net to reduce temperature during high temperature. Chemical prevention and treatment method: in the initial stage of strawberry anthracnose, 75% chlorothalonil wettable powder can be selected, or 2000 times of pyrimethrin suspension, or 1500 times of imipramine wettable powder, or 1500 times of difenoconazole water dispersible granules, or 1500 times of mancozeb wettable powder. Spray once in 7 days or so, 3-4 times in a row, and the medicament should be used in rotation. Special attention should be paid to the prevention or control of seedling raising in the open field after each rain.
