How to control diseases when planting red grape in summer? Please introduce the prevention and control methods of grape downy mildew, white rot, anthracnose and other diseases during the high incidence period in summer, downy mildew can lead to fallen leaves, withered branches, rotten fruit and even death. Therefore, in summer rainy season, it is necessary to strengthen the management of Hongti vineyard and prevent diseases in time. Clear the garden: if there is a disease in the vineyard, there is a lot of rain at this time, clear the garden at any time, remove the diseased leaves, branches and fruits from the garden, bury or burn deeply. At the same time, timely removal of weeds in the garden, in cutting off diseased branches, diseased fruit, should often wash scissors, and disinfection, to prevent cross-infection. Loose soil: summer and autumn rainy season, especially after heavy rain, Rain Water will make the vineyard soil surface hardening, poor soil permeability, resulting in lack of oxygen in grape roots, weakening tree potential, reduced stress resistance, thus susceptible to diseases. Therefore, the soil should be ploughed once in time before the rain or between the rain stops in order to improve the permeability of the garden soil. Treatment: continuous rain or high temperature and humidity, grapes are most susceptible to disease, should be a comprehensive observation in the vineyard once a day, see the onset of the disease, spray immediately. Such as downy mildew, if a disease is found in some parts of the garden, even on a grape plant, spray immediately. Clear tip: to pick the heart of the grape in time, wipe off the secondary tip in time. At the same time, some of the plants with too many new shoots should be removed, which is beneficial to ventilation and light transmission and improve stress resistance. Fertilization: too much Rain Water will often cause the loss of orchard fertility, weaken the tree potential and reduce its stress resistance. Therefore, in the rainy season, timely fertilization should be applied according to the soil fertility loss of the vineyard and the growth of grapes. Fertilization should be based on the principle of "eat less and eat more". Fertilizer should be applied less and frequently; extra-root topdressing is generally combined with spraying, and it is best to spray high-efficiency fruit foliar fertilizer alone.
