1.Prohibition of use during flowering period
During the flowering period of crops, foliar fertilizers should not be sprayed. The flowering period is the stage of pollination and fruiting, and fertilization during this period can easily burn flowers, which is not conducive to normal pollination and reduces yield.

2.Prohibited for use in high temperatures in the afternoon
Foliar fertilizer is an efficient nutrient solution component. If foliar spraying is carried out in high temperature weather, it will cause nutrient evaporation, and the rainy season will also reduce nutrient concentration. Both of these significantly reduce the utilization rate of foliar fertilizer

3. Do not use during the period when seedlings have not yet recovered
During the seedling stage of crops, most of them are just beginning to sprout or cannot be sprayed with foliar fertilizer after transplanting, because at this time the crops themselves are not only fragile but also not well adapted to external conditions. Generally, spraying nutrient solution can easily lead to the phenomenon of burning seedlings and leaves, which is not conducive to the normal growth of seedlings.

 

The effectiveness of foliar fertilization is directly related to temperature, humidity, wind speed, etc. It is best to choose a windless cloudy day or a day with high humidity and low evaporation before 9 am for foliar spraying. The most suitable time is after 4 pm in the afternoon. If it rains 3-4 hours after spraying, it is necessary to carry out supplementary spraying.
