Al TAHHAN INST. is a pioneer Institution of private sector for manufacturing different kinds of fertilizers and pesticides in Syria.
It was established in 1972 starting with the fertilizers manufacturing, the chelated liquid micro nutrients,

and developed in 1990 to be included the liquid (NPK) fertilizers, and in 1995 the institution had a new advanced stage in manufacturing liquid fertilizers, cooperating with Tessenderlo Kerley (U.S.A.- Belgium) to produce the specialized (NPK+TE) fertilizers to suit each plant's growth stage by various formulas: Thiosulfate balanced high Potassium, as well as high Phosphor.
Starting the pesticides manufacturing, firstly the public health pesticides in 1978 by a local trade mark and developed to be included (EC) formulations by under license from Mittchel Cotts Ltd. 1992, or by a local trade mark cooperating with FMC(U.S.A.).
The Institution began to produce the Rodenticides in 1985 in the form of powder, and pellets in 1994. The production of animal health pesticides by a local trade mark or under license from Novartis (Switzerland) and the agricultural powder pesticides started in 1994. Then (EC) formulations in 2000.
