Grasp the control of strawberry red root column rot
At present, the root rot of the red column is commonly found in strawberries grown in various regions. Mainly in the strawberry seedlings, the tip of the leaf margin changed from purple to purple brown, and then the whole plant wilted and died. The roots are dark brown and rotten, not long new roots. Cut open the main root, the center column becomes auburn, so it is called root rot in the red column. At present, we must pay close attention to prevention and control to protect strawberry roots. Specific prevention methods are as follows: After the strawberry is planted and survived, it is necessary to apply 800 times of Bacillus subtilis aqueous solution or 500 times of 50% methemozeptable aqueous solution of methicone, or 800 times of 72% of urea solution of urea manganese zinc wetted every 7-10 days. Or 1000 times 69% aqueous solution of magnesium adenoyyl WP, or 1500 times aqueous solution of 2.5% fludioxonil suspension, or 1000 times 30% aqueous solution of femolytic agent, or 800 times 47% WP wettable powder Aqueous solution for prevention and treatment. After onset, it must be applied continuously 2 or 3 times in order to control the disease and restore it to normal growth. In addition, if the strawberries grown in autumn and winter are exposed to rainy weather, they must be drained in time. After the rain, timely application of the above-mentioned fungicides at the roots for prevention and treatment to protect the root system can reduce the incidence. medical products Anesthesia Medical Co., Ltd. , https://www.honestymed.com
