摘要：

A study was conducted during rainy (kharif) season of 1997,1998 and 1999 to evaluate the different fungicides for control of leaf blight of menthol mint (Mentha arvensis L.) caused by Alternaria alternata (Fr.) Keissler and to determine most economical optimal application schedule. Chlorothalonil provided maximum disease control, though the other fungicides mancozeb, thiophanate-methyl and copper ox chloride were also effective. The chlorothalonil-sprayed plots gave 45% greater yield of essential oil compared with the unsprayed plots. Three applications of chlorothalonil at 15-day intervals provided economically acceptable disease control with maximum increase (40%) in essential oil yields and total net returns (Rs 7 700).
