Effect of benomyl on the control of black berry disease of black pepper Piper nigrum in Sarawak

Kueh T. K ., . and Chang S.H., . (1986) Effect of benomyl on the control of black berry disease of black pepper Piper nigrum in Sarawak. [Proceedings Paper]

Benlate benomyl 50 WP at 0.05 a.i. Delsene 75 WP carbendazim at 0.05 and 0.1 a.i. and Delsene MX 200 carbendazim 6.2 plus mancozeb 73.8 at 0.1 and 0.2 a.i. significantly increased green berry yield spike length number of berries per spike berry size pericarp thickness fresh and dry weight of berries having diameter greater than 4 mm. The number of Colletotrichum spots per berry was reduced. The quality of berries in terms of oleoresin piperine volatile oils and macro- and micro-elements was similar to the untreated check. In the four other field experiments Benlate at 0.05 and 0.1 a.i. Delsene MX 200 at 0.1 and 0.2 a.i. Combat Carbendazim at 0.1 and Tilt propiconazole at 0.05 showed positive effect on green berry yield increase and spot reduction. There was no indication that Colletotrichum piperis and C. capsici isolated from black pepper growing areas where Benlate 50 WP had been used in the past years developed resistance to Benlate.

Abstract

Benlate benomyl 50 WP at 0.05 a.i. Delsene 75 WP carbendazim at 0.05 and 0.1 a.i. and Delsene MX 200 carbendazim 6.2 plus mancozeb 73.8 at 0.1 and 0.2 a.i. significantly increased green berry yield spike length number of berries per spike berry size pericarp thickness fresh and dry weight of berries having diameter greater than 4 mm. The number of Colletotrichum spots per berry was reduced. The quality of berries in terms of oleoresin piperine volatile oils and macro- and micro-elements was similar to the untreated check. In the four other field experiments Benlate at 0.05 and 0.1 a.i. Delsene MX 200 at 0.1 and 0.2 a.i. Combat Carbendazim at 0.1 and Tilt propiconazole at 0.05 showed positive effect on green berry yield increase and spot reduction. There was no indication that Colletotrichum piperis and C. capsici isolated from black pepper growing areas where Benlate 50 WP had been used in the past years developed resistance to Benlate.
