Works but handle with care

It does the job against fungal infections on my chili peppers, but you really need to wear gloves and a mask. Strong stuff.

Standard agricultural grade

Exactly what I needed for my rice paddies. The purity is consistent with what we use on the farm. Great value for the price.

Perfect for homemade fungicide

I've been making my own Bordeaux mixture for years. These crystals are high quality and mix perfectly with lime. Highly recommended.

Good quality, fast shipping

The product arrived well-sealed. I applied it to my citrus trees as directed. It seems effective, though I need to wait a bit longer for full results.

Excellent for my grape vines

I used this to make Bordeaux mixture for my grape vines this season. The crystals dissolved easily and the results were fantastic. No more mildew issues!

A: The package includes general usage guidelines. However, dosage varies significantly by crop type and disease severity. We recommend consulting local agricultural extension services for precise mixing ratios.

A: Yes, it is widely used on edible crops including chili peppers, grapes, and citrus. However, strictly adhere to the pre-harvest interval guidelines listed on the label to ensure safety.

Q: How do I prepare the Bordeaux mixture using these crystals?

A: Dissolve the copper sulfate crystals in water in one container and slaked lime in another. Then, slowly pour the copper solution into the lime solution while stirring constantly. Never reverse the order.

A: If stored in a tightly sealed container in a cool, dry place away from humidity, the crystals can remain stable and effective for several years.
