Can glucose be sprayed in hot weather during grape discoloration?

Of course. Grape color change period is an important period for grape growth and development. At this time, the grape fruit began to change color and the sugar and acidity gradually increased. High temperature weather will reduce the sugar and acidity of grape fruit and affect the quality and yield of fruit. Therefore, measures can be taken to reduce the adverse effects of high temperature weather on grape fruits, including spraying glucose. The spraying time of glucose should be carried out before the high temperature weather, about one week before the grape discoloration period. After the high temperature weather, the effect will be greatly reduced.
