FREQUENTLY ASKED QUESTIONS
How is a systemic fungicide different from other fungicides?
- A systemic fungicide can be sprayed directly on the foliage or applied to the root zone.
- After initial application, a systemic product will rapidly absorb and then work throughout the entire plant. Other fungicides are contact fungicides: the product must make direct contact with the disease area in order to effectively treat the disease.
What diseases will Plant Doctor control?
- PLANT DOCTOR is very broad-spectrum and controls most diseases like anthracnose, black spot, downy mildew, fire blight, stem blight, rust, phytophthora (root rot) and pythium.
What makes Plant Doctor so unique?
- Plant Doctor is both a preventative and curative.
- It will control pythium & phytophthora (root rot) as well as powdery mildew (foliar disease).
- After 14-21 days, it converts into nutritional potassium and phosphorus, that the plant consumes as nutrients and nothing is left in the ground.
- It is also a bio-stimulant; once inside the plant, it stimulates the plant’s metabolism resulting in more plant vigor, increase bloom and crop yield, and increasing stress resistance.
- The active ingredients have been used for years in commercial growing and agri-business markets with great success.
How does it work?
- By stimulating the metabolism and plant vigor to such a high degree the plant staves off and overcomes disease.
- Pathogens such as phytophora cannot process the active ingredient in Plant Doctor, though they will attempt to process it as a nutrient. This effect shuts down the pathogens’ cells, terminating the disease.
What about environmental impact?
- Plant Doctor is an EPA registered fungicide with minimal impact on the environment and low risk to user and non target organisms, it is beneficial and nutritional to plants.
- Re-entry time is as soon as spray has dried upon the leaves, however, if you are treating a fungus we recommend you allow the product to work thru the plant to ensure remedy.
