I tried Biosys last year on half my leeks in pots. The half treated with Biosys were definitely healthier, and more tolerant to the stressful growing conditions we had. This year I'm growing all my leeks with it from start to finish.
My onions would always suffer badly with Botrytis. Since using Biosys early on in the greenhouse, and once a month in the beds, I've barely lost any. That says it all!
After prepping the soil with green manure, the only other product I used on my leeks and onions was Biosys microbial tea. The quality of the leeks was outstanding, I won't be growing without it again!
