DefenZa is a gentle, organic based, foliar micronutrient fertilizer that immediately boosts plant growth, recovery from disease, and crop production. DZ delivers a proprietary blend of natural, highly mobile, ionic nutrients, Nitrogen, Phosphate, Potassium, Copper, Zinc, Boron, Iron, Sulfur, Carbon, Calcium, plus naturally occurring Organic & Amino Acids.

DZ works with each plant’s natural immunity, providing organic tools to help plants defend against crop diseases ranging from fungal/bacterial spore germination to systemic disease phases - such as Anthracnose. DZ’s unique nutrition quickly improves photosynthetic efficiency, and strengthens the plant’s immune system, making the plant healthier, more productive, and far more resistant to disease.
No. DZ does not require any buffering, and no chemicals of any kind should be added to either the concentrate or the final ready-to-spray (RTS) solution.
No. DZAzul must be diluted at 1:200, with fresh water first. Then DZBoost is added to that solution, mixed thoroughly, and then spraying can begin.
After diluting to the required 1:200, the RTS is effective, should be used immediately, and will remain effective for up to 2 hours.
The best time to apply DZ ready-to-spray (RTS) solution is when temperatures are cool, and the plant stomata are open--early morning, until about 10:00 a.m. (10:00), or late afternoon, after about (17:00), when temperatures are cooler than during the highest heat of the day.
No, if the plants have too much water on their surface, DZ will become too diluted to be effective. For best results always make sure there is no chance of rain before, and at least 24 hours after applying the product -- 48 hours is preferred. Leaves should be dry and free of dew or mist prior to spraying.
Coffee Leaf Rust (CLR or La Roya). Nearly $500,000,000 (usd) of coffee was destroyed by CLR in Latin America in 2012/13. DZ is being sprayed to successfully combat and eliminate this disease.

Yes. DZ is a certified organic by Kosher Organics

No. With multiple modes of topical and systemic action, DZ is and will continue to be effective against many pathogens otherwise resistant to typical fungicide and bactericide groups.

DZ is first and foremost a contact product, so it does not rely on systemic uptake as its primary method of action. No resistance to DZ occurs. In fact plants thrive on the DZ micronutrient infusion, and it can (and should) be applied as part of a regular maintenance schedule.

DZ increases crop yields, stimulates plant growth, boosts plant immunity, protects plants from a host of fungal and bacterial diseases, optimizes crop production from seedling through harvest, destroys fungal spores to slow down and eliminate re-infection.
This depends on the conditions of the affected crops. As a general rule, when there is severe infection, we recommend 3-4 sprays at 30-day intervals. From that point a maintenance regimen should be employed, with 1 spray every 90-120 days depending on the crop, the type of pathogen/s, weather conditions, and if the pathogen is lingering and persistent.
