Ed Rosenthal's Zero Tolerance

Ed Rosenthal’s Zero Tolerance™ offers advantages over other natural products, and poisonous pesticides and fungicides. ZT leaves no residue (unlike Neem oil) because the highest quality food grade oils of cinnamon, clove, rosemary, and thyme evaporate fully. It is safer for the garden than Pyrethrum, which is toxic to fish and reptiles.

Ed Rosenthal is recognized worldwide as a leading botanist. He was one of the first American writers to travel to Holland, bringing European knowledge and sophistication about indoor cultivation to the US through his books and columns.

Through his research Ed discovered that soft-body insects such as spider mites, aphids, and whiteflies do not infest certain plants. Other plants are resistant to powdery mildew, grey mold and other fungus.

The plants were giving off a scent that warned insects that if they come too close, they would die. Nature's chemistry, developed over millions of years was signaling, “This is a no pest zone."

Ed studied how some of these plant oils destroyed the exoskeleton while others deteriorated the nervous system.

By combining the oils from these fragrant plants he came up with a potent blend that will eliminate pests quickly.

Ed's products use plants to protect your plants. 100% natural they are safe to use near family and pets. Made from plants, Ed's products even smell good.

“After years of research I have developed natural garden solutions that I know you will be pleased with. Use them in your indoor, greenhouse, and outdoor gardens, they are safe when used as directed and contain no weird chemicals.” – Ed
