    White powdery mildew appeared on quite a few of my plants and was killing them off.
    Purchase this, but the spray end was kinda faulty and took me longer than ever to spray the plants. However, i persevered every 4 days until the plants have no more of that powdery white mildew. I think i will purchase the next bottle from the shop just to make sure it can spray properly

    Each year we loose plums to mould as the tree is in a damp area. I bought this spray with morse than a small degree of schematism. Very surprised with how effective it has been. Sprayed the fruit weekly and we have lost only a few plums. We have so many we are giving them to neighbours. Highly recommend this product.

    I’ve used this product in the past and it was very effective, but I’ve purchased two bottles lately and it’s all but useless!
    I’ve had a similar experience as a previous reviewer who stated The original bottle had a green spray top and a distinct, strong smell. However, the bottles I received came with white spray tops and were unsealed. Additionally, the liquid seemed diluted, as it had a much milder scent. Have applied it two or three times and it still hasn’t had any effect on the black fly on my plants !
