Prevention and treatment of Verticillium wilt, can double the peach, Premature senility, rotten peach not more than 1% to 2% 1 bag of agarwood (10 g) + 1 bag of streptomycin 72% (15 g) + sulfuric acid Copper 15 grams, + a small amount of vinegar melts (about 0.3%) + 30 kg of water spraying and irrigation root. Such as spray root better. If you add 20 grams of zinc fertilizer, boron 20 grams (irrigation root 40 grams), the effect is better. Cotton is not easy pests. Fusarium wilt disease, Verticillium wilt various diseases, spraying 1-2 times to cure. Pest insecticide in the mixture plus fenpropathrin (pyrsarone) and imidacloprid for several months (six months) no worms, cotton pests can be completely eliminated. Herbicides can make strong grass (water peanut, tendon grass) root rot after 10 days, the season no grass. Significant drought, flooding, low temperature, high temperature, hail and premature aging. From the beginning of flowering, adding 40% gibberellic acid 0.5 to 1 g spray in the mixture, 1 to 15 to 20 days or so, spray 3 to 4 times, cotton double peach, each bolting significantly larger , Early fried peaches, early maturity. In September every day under the conditions of rotten peach does not exceed 1% to 2%. Proved by practice: 1, cotton production in Jingyan County, Sichuan Province, which was unfit to grow cotton
