An Economic Feasibility Study on the Use of Trichoderma Powder to Control Sclerotium Root and Stem Rot of Tomato.

Abstract

The main objectives of this research are to analyse the cost and revenue of tomato production and to study the possibility of commercial production Trichoderma powder to be used to control tomato root and stem rot caused by Sclerotium rolfsii Sacc. The results of the study showed that average production cost and revenue of tomato was estimated at about 6,518.89 and 8,416.03 baht per rai respectively. The possibility of production Trichderma power has some potential by comparing economic loss of the disease with the expenditure of using the powder and its efficiency to control the disease ; and comparing average production cost, output quantity and net profit in case of using with and without using the powder. However, such possibility potential will be low or high depends upon several factors, such as tomato’s sales price, Trichoderma powder’s potential demand, the powder’s efficiency to control Sclerotium Root and Stem Rot of tomato and various diseases of other economic crops and promotional sales cost of the powder.
