Plant Pesticides

Best way to prevent diseases on plants is to grow disease-resistant varieties.

Resource Guide for Organic Insect and Disease Management from the New York State Agriculture Experiment Station

Bt Bacillus thuringiensis - a naturally occurring bacteria in spray or powder form used to control caterpillars and larva on plants.

Neem - plant derived botanical pesticide in spray form to kill larva and insects.

Insecticidal Soaps - potassium salts of fatty acids used to kill soft bodied insects like mites.

Horticultural Oils - petroleum or vegetable-based oils used to smother insects and diseases.

Best way to prevent diseases on plants is to grow disease-resistant varieties.

Bicarbonate -- potassium and sodium fungicide used to control powdery milder. Mix once ounce of baking soda with one gallon of water to control powdery mildew on roses.

Copper - mineral fungicide used to control diseases on plants.

Good luck out there!
