Phenothiol

Phenothiol is the ester of MCPA-thioethyl, and it is an innovative auxin, developed by Sipcam Oxon for a variety of crops and targets, offering great benefits for the farmers when used as a plant growth regulator

Class

Auxins

Its action is linked to the metabolism of the nucleic acid, which is stimulated in the growing organs, also affecting the balance of ascorbic acid, that of some B vitamins, minerals and enzymes (peptidases, phosphatases, catalases, cytochrome oxidases, etc.), as well as the content of chlorophyll and other natural pigments. It has a direct effect on respiration and the metabolism of phosphorous and nitrogen. It stops or slows down (depending on the amounts received by the plant) the activity of the cells that cause the elongation of growing organs (affecting the apical meristem), although it does not prevent its expansion, that is, it inhibits apical growth in favor of axial growth. It causes delay in foliar development but increases its vascular tissue. It has a direct effect on the formation of cell membranes, thus activating the thickening of stems and peduncles by stimulating the division of cambium cells. It easily penetrates into stems and roots, being absorbed by the protoplasm, migrating through the parenchymal tissues to the vascular channels, favoring their development and, in this way, translocating with the ones assimilated to the different points of the plant where they are necessary, roots, shoots, flowers and fruits. It stimulates the photosynthesis process (depending on the amounts received by the plant), as well as the absorption of nitrogen and phosphorus. An adequate auxin level compensates for the effects of ethylene, preventing aging of the plant.

Straight products	Phenothiol 2% w/v, (SL) - Soluble concentrate
Area	Spain, Greece, Egypt
Benefits	HF CALIBRA is a straight formulation of phenothiol, formulated with activation and penetration agents to increase the size or caliber of various citrus varieties and to prevent fruit from falling. Used in apple trees, it increases the size of the fruit. In apricot, peach, nectarine and plum trees, the final size of the fruit increases and it accelerates ripening.

Mixtures	Gibberellic Acid 0.5% w/v + Phenothiol 1% w/v, (EC) - Emulsifiable concentrate
Area	Spain, Italy, Morocco, Algeria, Egypt
Benefits	FENGIB is a product in which phenothiol is formulated as a ready-mix with gibberellic acid in different proportions. FENGIB is mainly used in citrus fruits. By its composition, FENGIB allows the development and the cell multiplication, increases flowering, favors the fixation of fruits, their magnification and uniformity of caliber, as well as production within trees. It increases the profitability of vegetable crops, increases fruiting, guarantees early ripening of fruits, improves size uniformity, and increases the production of tomatoes and strawberries. By combining two active substances (gibberellic acid + phenothiol) it is possible to compensate the unwanted effects of each one when used in isolation: on the one hand, the depressive effect on size caused by gibberellic acid when it stimulates fruit set, is compensated by the action of phenothiol. This explains the homogeneity and better distribution of sizes of the fruits produced. on the other hand, the vegetative stimulation caused by gibberellic acid is slowed down by the effect of phenothiol stopping or slowing down cell development in growing organs. This explains the temporary stop of the growth of shoots and leaves in favor of the fruits in formation and development stages.
