Flowering and fruit set: two crucial phases for tree crops

Flowering, pollination and fruit set are phenological processes that induce the plant to produce endogenous metabolites and to consume a lot of energy in order to favor and facilitate the transformation of flowers into fruits.

Furthermore, oxidative, thermal and water stresses frequent in the flowering, pollination and fruit set phases can negatively influence the fruit set percentage, resulting in reduced pollen formation, difficulty in growing of the pollen tube and limited fecundation.

Without the necessary nutritional supplements, the necessary amounts of metabolites and energy are not reached, causing flower abortions, fruit drop and negative effects on productivity.

PROTEO INTERNATIONAL S.r.l. has developed products that can be successfully used in these crucial phases by foliar application:

• VALTAN: liquid, seaweed extract and yeasts;

• STIMOFOL: liquid, N-acetyl-thiazolidine-4-carboxylic acid at 5% w/w;

• CALBOSOL: powder, Calcium complexed with carboxylic acid plus Boron;

• FOSFOCAL: liquid, Phosphorus and Calcium in a 4:1 ratio with micronutrients;

• FOLIBOR L: liquid, Boron at 11% w/w.
