BTK BIOLOGICAL INSECTICIDE

(3 customer reviews)

Price range: $17.95 through $49.95

Although the main focus in recent years has been on gypsy moth caterpillars, BTK is also an effective weapon to use on tent caterpillars, leafrollers, tomato hornworms and such like. BTK refers to the active ingredient in this product–Bacillus thuringiensis var. kurstaki. This is NOT a chemical pesticide, but a natural bacteria microorganism. As soon as caterpillars ingest it, they stop feeding and die within days. BTK can be sprayed on all trees– fruit, shade and evergreen as well as vegetable plants. Birds, animals and people are not endangered, but please avoid spraying milkweed plants, as monarch butterfly larvae feed on this plant only.

Mix 33 ml per 10 liters water and spray in late afternoon as direct sunlight breaks down the active ingredient.

What is Orchard Grade?

An 'orchard grade' is a tree that may be somewhat shorter, slightly crooked, or a bit scratched, or for some other reason is not a perfect front lawn specimen. These trees will work just as well in an orchard as a first or number one would, since they still produce the very same fruit.

What is a 2 year old tree?

A '2 year old tree' is one that has grown an extra season in our nursery field.

All our trees are planted in the field in the spring as rootstock. They are grafted in August of the 1st year. Most of our trees are dug out in November of the 2nd year. Some trees are in the ground for another season. We dig these in November of the 3rd year. These are considered to be '2 year old trees'.

A '2 year old tree' has bigger roots, a thicker trunk, and more branching (They might start fruiting a year earlier).
