@shonin@c.im Wow, this has been a lesson for sure, be we have receiving those fungicides and bacterias on our crops but some time we used to use a combination of Nitrate, phosphate and potassium (NPK) But it my first time to hear that also Superphosphate can also kill black spots and wilt on our tomatoes. But l would like to know, what tools do you use when you are watering the fertilizer and pests control because it's unfortunately that fertilizer, tools used irrigation and pests we need..........
