Preventive measures: Deep ditch sorghum, the implementation of mulch covered, generally 30-40 cm deep ditch, while covering the mulch near the bottom of the ditch, in order to reduce the incidence of fruit and soil contact, do a good job in drainage to reduce hazards. Remove dead leaves and diseased leaves in time.
The application of organic fertilizers, especially bio-fertilizers “Tudelaâ€, will improve the soil. Balance the amount of nitrogen, phosphorus, and potassium, control the amount of nitrogen fertilizer, prevent leggy, and at the same time, plant the plant in close numbers. The number of acres per plant should be controlled within 8,000 trees to facilitate ventilation. Appropriate amount of micronutrient supplementation to improve disease resistance. Spraying of available boron, copper sulphate and manganese sulphate etc. at the beginning of the growth of the young leaves and bud stage. In the growth period of 7-10 days, once sprayed with marine biological immunity agent 600 times Haitian force spray 3-4 times in order to enhance the disease resistance of strawberries.
Chemical control: The principle is biological + chemical drugs, internal resistance + external suppression methods.
Powdery mildew 25% triadimefon wettable preparation 3000-5000 times + Haitian force 600 times fluid, or 10% Shihai high water dispersible granules 2000-2500 times + Haitian force 600 times, or 12.5% ​​Myclobutanil EC 1500 times Fungicides are alternately controlled.
Botrytis cinerea can be sprayed with 500mg of polyoxomycin wettable powder 600 times of 600 grams of shixacil, or 600 times of 50% milamidamine in the growth phase (flowering avoidance period), pay attention to alternate medication.
Single-use samplers are used for sample collection, transportation and storage, etc. Sampling swabs are composed of Swab rods or swab heads, and are divided into cotton swabs or flocking swabs. The swab head is made of chemical fiber (polyester, rayon, etc.), nylon and other non-cotton, non-calcium alginate materials; the swab rod is made of PP, PS, ABS and other non-bamboo/wood materials. The breaking point is located about 3cm and/or 8cm (or any position) from the tip of the swab, which is easy to break.
