At present, it is strawberry transplanting period. Strawberry seedlings and transplanting period, easy to appear powdery mildew, gray mold and anthrax, etc., prevention and treatment is not timely, and sometimes all of the strawberry seedlings were destroyed. The prevention and control techniques for these three major diseases are now described as follows: Food Additive Monosodium Glutamate 98% Cheap Food Additives,Good Food Additive,Food Additive Bha,Additive Monosodium Glutamate JILIN COFCO BIO-CHEM AND BIO-ENERGY MARKETING CO., LTD , https://www.cofco-biotech.com
First, strawberry powdery mildew. The key prevention period for open field cultivation is the flowering period before flowering. Prophylaxis: 100 times taiwan 1500 times or 25% 100 gram 1000-1500 times, locust bacteria 500-600 times spray, 7-10 days once.
The prevention period for the cultivation of small bow sheds is around December and before and after the second year of May. In early onset of disease prevention and control, Tsui Bay is 3000 times, 50% is 1000-1500 times, and Kaiser is 2000 times and 500 times the standard. Runge 500-600 times. Pay attention to the use of the drug, do not use the same type of drug more than twice.
Second, strawberry gray mold. Bacteria are most susceptible to disease when they are wet and around 25°C.
To prevent the main, the best period of application for the first strawberry inflorescence flowering more than 20% and the second inflorescence just flowering. Pharmacy selection: Kai Ze 1200 times or 1000 times or 50% Nongli Ling so 1000-1500 times, 500-600 times Longke bacteria, continuous control twice, alternating medication. When the disease is severe, Ketser can choose 1200 times more than BioTex 1500 times or Kai Ze 1200 times, 50% make 100-1000 times more effective, and Dragon's bacterium 500-600 times.
Third, strawberry anthrax. Occurred in the nursery period and the initial stage of colonization, the pathogenic bacteria infection temperature of about 30 °C, will quickly spread the disease, continuous rain or showers or typhoons, can easily occur. It is necessary to use prevention as the main method, and use Baitai 1500 times, 25% to 100 times 1000 times or Dragon's bacteria 500-600 times, once every 7-10 days, and it is better to use sun protection seedlings or cover shade nets. For the diseased plants, 2000 times and 25% of Kerun were used to control 100-fold 1000-fold and 50%-1000-1500 times.
