Botrytis cinerea is a disease of low temperature and high humidity, with low temperature and low light in winter. Slow or non-healing of vegetable wounds during plant adjustment and pruning is an important cause of gray mold. In addition, the winter environment is not conducive to the growth of vegetables, and the plant's resistance to diseases is reduced, resulting in repeated infestation of gray mold. Botrytis is an airborne disease, and once it occurs, the disease can spread particularly quickly.
The typical symptoms of Botrytis cinerea infected with gray mold are that the peel is gray and white, and has a thick layer of gray mold. It is watery and rot. The disease onset begins at the tip of the leaf and extends inwards along the veins, forming a "V" shape. distinct.
Grey mold needs to be protected in advance, and 100 ml of 100 ml of Luna Sen 100 ml + Rui Jia Jia Irrigation roots about 1200, each medlar 150 to 250 grams of water, control period of up to 45 days. Once the vegetables are infected with gray mold, we must first reduce the number of pathogens, and spray Lunasen 1500 times + Ruijiajia 1500 times on the leaves to kill pathogens on the surface of the plants. Their good systemic absorption can kill the plants better. Bacteria, reduce secondary infection. Spray again after 7 days to lengthen the validity period. After the drug is applied twice, the effective period is more than 40 days.
The occurrence of gray mold is also directly related to the weak growth of plants and the poor resistance to disease. Many vegetable farmers rescued by irrigating with water, but they did not achieve very good results because it was a root problem. The root system was weak and there were no new roots. Therefore, measures were taken to promote root and rejuvenation. Chong Shi Yi Wei 500 g/mu + Ciba Boron and Zinc Fertilizer 150 g/mu, Yi Micro Energy can improve the growth environment around the roots and achieve the purpose of stimulating rooting; Ciba and zinc fertilizers supplement boron and zinc, and stimulate boron to stimulate capillary elongation Zinc supplementation enhances the plant's resistance to stress. The purpose is to raise roots and protect roots, reduce root diseases, increase the resilience of the gardenia, stimulate rooting, alleviate snoring and stem space and fruit emptying caused by poor root systems, and improve crops. The effect of the late production is good.
