The Lost Acre puts Isaria to Work

A New Way to Bring Isarid Home

Isarid HG is an entomopathogenic fungus formulated for home and garden growers, now available in a 4oz size built for houseplants, backyard beds, and container gardens rather than commercial acreage. It brings the same biological insect control that greenhouse professionals have relied on for years into a format made for the home grower.

Robert Bell of The Lost Acre reached out after using Isarid with success on his own property, and he's now featuring Isarid HG on his YouTube channel, walking through how this biological insecticide fits into a small scale flower farm and garden setting. Watch the video below to see it in action.

What Isarid Does

Isarid HG contains the entomopathogenic fungus Isaria fumosorosea strain FE 9901. The spores land on a pest, attach to its body, and begin to grow. Once a spore penetrates the pest's outer shell, the fungus spreads through the body and the pest stops feeding, becomes inactive, and dies. It works against a wide range of soft bodied problems including whiteflies, aphids, and thrips, along with mealybugs and fungus gnats.

Because Isarid works through direct physical infection rather than chemical toxicity, it is safe for pollinators and does not harm beneficial insects. That makes it easy to fit into an integrated approach, whether you are treating a windowsill of houseplants or a full cut flower garden.

A Size Made for Home Growers

Isarid HG mixes easily for spot treatments or broader applications across houseplants, a home garden, container plants, or a small flower operation like The Lost Acre.
