- Enhancing growth and morphogenetic processes
- Increased yields and improved presentation
- Formation of higher quality fruit
- Setting of flower buds for the next year
- Avoiding alternation of fruitful and barren years
Why is thinning of fruit crops required?
Chemical thinning of the ovary is the method that allows obtaining high-quality fruits and at the same time provides intensive flowering for the next year. This method also provides good and uniform yields over the years, with the total yields of a well-thinned out garden over several years being higher than those of an unbroken garden.
The process of apple fruit formation lasts 16-18 months and covers two consecutive seasons, starting from the differentiation of the flower buds during their fruiting in the first season till flowering and subsequent fruit ripening in the next year.
Chemical thinning of the ovary helps the tree"s natural tendency regulate the fruit load itself by shedding weaker fruits, thereby promoting the growth of the stronger ones. This enables obtaining the yield of mainly commercial quality. Thinning out the ovaries contributes to better coloring of the fruit, reduces the likelihood of breakage of parts of the tree by the fruitage, helps notice the appearance of pests and diseases, and also prevents the weakening of the tree.

Thinning out the ovaries at the early stages of fruit development
Spraying of plants at the stage of the "hazel" fruit size (the fruit diameter is 12-14 mm)
Method of application
Procedure for the working liquid preparation
Prepare the working solution immediately before use.
Fill the sprayer tank half full with water, add slowly the full dose of the product with stirring, rinse the canister with the product residue several times with water. Add the flushing water and the remaining amount of water to the sprayer tank with stirring. Continue stirring during the application to ensure the working liquid homogeneity.
Prepare the working solution and refill the sprayer at designated places that are to be deactivated later. Spraying should be carried out in calm weather.
Use garden remote sprayers OPV-1200, OP-2000, OVH-28, OZG-400, or equivalent.
When used according to the regulations for use, the product is not phytotoxic for orchard crops.
