Pyganic insecticide is a very short-lived contact insecticide that is approved for organic use and is OMRI certified.
It contains natural pyrethrins derived from chrysanthemum plants and can be sprayed right up to the day of harvest. PyGanic is very useful for quick knock-down of pests such as Japanese beetle adults, mites, aphids, and leafhoppers.
It breaks down very quickly when exposed to sunlight. Avoid spraying when bees / pollenators are actively foraging.
Hops are not specifically listed on the label. However -"may be used on most crops because its active ingredient is exempt from tolerances when applied to growing crops". Hops fall under the category of Outdoor Grown Crops.
Note that PyGanic is a non-selective insectide and will kill beneficials and predator insects as well as the target pest.
I would recommended to reserve its use for knockdown when pest levels go out of control. As with all pesticides; read the label carefully before use.
