- Thinex™

Thinex™ is a new fatty acid based blossom thinner that promotes return bloom (annual bearing) and increased fruit size and quality. Thinex allows apple growers to reduce the need for costly hand thinning, without sacrificing fruit yield or quality.

CHEMISTRY/ MODE OF ACTION

Thinex is based on pelargonic acid, a naturally-occurring fatty acid found in many fruits. When used according to label instructions, Thinex thins unpollinated blossoms by damaging the flower's reproductive parts (specifically the stigma), which inhibits pollination. Fertilized flowers will not be removed by Thinex.

BENEFITS OF BLOSSOM THINNING

Blossom thinning with Thinex is the first step in a multi-step program to adjust the fruit load in an orchard. The grower can then adjust crop size as needed with petal fall and/or post-bloom thinning agents to achieve the desired fruit load with reduced hand thinning costs. Advantages of using Thinex over other bloom thinning products include:

Easy to Use:

• non-corrosive to equipment and clothing.
• results generally are visible within 1-4 hours after application.
• can be used up to 100% bloom.

Low Toxicity to Non-Target Organisms:

• residues are non-toxic to bees; bees will return as soon as blossoms have dried.
• does not induce mite flare-ups.
• based on a naturally-occurring active ingredient.
• low toxicity to workers
• brief re-entry period (12 hours).
