hello everyone. I would like to receive information from grape producers. My goal is to grow grapes without using chemicals and not poison the world. What is your jwa usage amount from the moment the grapes reach the size of chickpeas and until the end of the harvest. How much jwa do you put in 100 liters in your fight against thrips, empoasca and red spiders. I doubt that jwa will leave marks on bunches of grapes. please help me
