Sparse spikes (ie, sparse flowers) grow at the shoot for a few days after emergence, according to the planned yield, the excessive spikes are removed, the good flowering spikes are selected, the common branches are left with 2 spikes, and the golden branches stay 1 spike. Weak branches do not leave ear. Combine the whole ear, timely picking the tip and removing the panicle. The fruit thinning time is set after the flowering and fruit setting, and it is usually carried out immediately after the size of the fruit is like the size of the soybean and can be identified. Remove pests and fruit, malformed malformed fruit, and seedless grains, and the fruit in the top of the fruit, sandwiched between the ears. Generally, 30-50 grains per panicle are more suitable.
It is Non-ionic surfactant which can reduced the spray drift. Which makes more pesticide to the target.
While it also can reduce the surface tension of the water. In order to have great wetting and penetration function. And widely used in the pesticie, fungicide, insecitide and herbicide.

Why do grapes need thinning and thinning
Grapes are overloaded. They not only consume nutrients, affect the growth of fruit, but also lead to different sizes of fruits, irregular fruit shape, difficulty in coloring or coloring, inconsistent ripeness, and deterioration of quality. They also tend to cause premature aging of tree vigor. Therefore, it is necessary to rationalize the fruit thinning and fruit thinning, so that the plant load tends to be reasonable, increase the size of the fruit, achieve the purpose of high yield, stable production, and improved fruit quality.
