Monterey® B.t.

It is a naturally occurring material based on the bacteria Bacillus thuringiensis subspecies kurstaki. These naturally occurring products were discovered in the 1960’s and have been used ever since for worm and caterpillar control. When the insects ingest the product, it causes a disease in their gut, causing them to stop feeding and eventually die. The bacteria in Monterey B.t. is 98.35% active (at least 6 million viable spores per mg.)

All fruits and vegetables, ornamentals, shade trees, flowers etc.

Only Lepidoptera insects (caterpillars and worm type insects.)

Mix with water and apply with a sprayer at 5-7 day intervals while insects are active. The product must be eaten by the insects to be effective. It is best to treat when the insects are small. It can be used up to and on the day of harvest.

Yes, Monterey B.t. is OMRI Listed for Organic Gardening.

For fruits and vegetables, use 1.5 oz. per 3 gallons of water (1 Tbsp per gallon) and apply to 1000 sq ft. On ornamentals, apply at 2 oz per 3 gallons of water (4 tsp per gallon).

Once mixed with water, use all the spray mixture within 24 hours. Thorough leaf coverage is necessary. This product is slow to kill the insects so you may see them after applying the product, even though they have quit feeding. Always read entire label before use.
