BotaniGard 22WP – Beauveria Bassiana Biological Insecticide

BotaniGard 22WP is a professional-grade biological insecticide powered by Beauveria bassiana strain GHA, a naturally occurring beneficial fungus used by commercial growers for decades to control soft-bodied insects and resistant pest populations.

Unlike conventional chemical insecticides, BotaniGard works by infecting insects on contact, helping reduce resistance issues while remaining compatible with many integrated pest management (IPM) programs.

Effective Against:

✔ Whiteflies
✔ Aphids
✔ Thrips
✔ Fungus gnats
✔ Root aphids
✔ Mealybugs
✔ Psyllids
✔ Leafhoppers
✔ Weevils
✔ Lace bugs
✔ Chinch bugs
✔ And many other soft-bodied insects

Why Growers Use BotaniGard 22WP

✔ Biological insect control using Beauveria bassiana strain GHA
✔ Excellent resistance management tool
✔ Safe for use up to day of harvest
✔ Works well in greenhouses, indoor gardens, hydroponics, coco coir, and soil grows
✔ Compatible with many pesticide rotation programs
✔ Used by professional greenhouse growers for more than 20 years

How It Works

BotaniGard spores attach directly to the insect’s outer surface (cuticle), germinate, and infect the pest naturally. Insects stop feeding and die shortly after infection.

Because the mode of action is biological and physical, pests are far less likely to develop resistance compared to many traditional chemical insecticides.

Common Uses

BotaniGard 22WP is widely used for:

Houseplants
Indoor gardens
Greenhouses
Hydroponic systems
Coco coir grows
Organic-style growing programs
IPM pest prevention and rotation

Natural and Organic Controls

Organic methods are preferred with root aphids since most insecticides are only moderately effective and may just end up making your garden more vulnerable to other pests by removing beneficial insects. Young and/or heavily infested plants should be culled since replacing them will be less costly in the long run.

BotaniGard 22WP

(11 grams BotaniGard per gallon water)

There is a reason this product is at the top of our list. BotaniGard is a mycoinsecticide, or insect killing fungus. It can be inoculated in the root zone and kills all stages of crawlers (it kills fliers but they are less likely to come in contact). Aphids are unable to build up an immunity to the mycelium, and it’s perfectly safe to use up to the day of harvest. So while it isn’t cheap, and won’t kill them all in one shot, Botanigard is definitely worth the cost.
