Abstract

The research was conducted in the Soulowe of village, District Biromaru, Sigi. Experimental design used was Randomized Block Design (RBD) with 3 (three) treatments and 5 (five) replications, in order to obtain 15 units of the experiment.  Each treatment is based on the differences in varieties. These varieties are varieties Bonanza, Paramita and Kumala. The variables measured were the intensity of the attacks and the rate of infection diseases. The first observation made at the time the plant was 14 days after planting, subsequent observations made at intervals of once a week as much as 7 times. The results of this study showed that the difference in response of resistance varieties Bonanza, Paramita and Kumala against downy mildew caused by the fungus Peronosclerospora maydis. The highest attack intensity was found in varieties Bonanza followed by Kumala varieties, while the lowest was found in varieties Paramita. The highest disease infection rate was varietas Bonanza, then followed by Kumala varietas, and then Paramita varieties that have the lowest disease infection rate.

Abstract

The objective of this study is to know the ability the fungus Trichoderma sp. as antagonistic to fungal pathogens Alternaria porri (EII. Cif.) on shallot. This study was conducted in the Laboratory of plant pests and Disease Department (HPT), Agriculture faculty  of Tadulako University, Palu in Plant Central Sulawesi. This study used the isolation and identification of fungal pathogen A.Porri on onion and antagonism test of Trichoderma sp test against mold growth A.porri, with 2 treatments and 5 replications so that there were 10 experimental units. Local isolates of Trichoderma sp. Used in this experimen were derived from two institusion the Laboratory of plant pests and Diseases Faculty of Agriculture University of Tadulako and BPTP Biromaru. The result of this stady indikate that bolt of lokal isolate Trichoderma sp. quite effective in suppressing the growth fungi A.porri EII. Cif. disease-causing purple spots on the onion crop in-vitro, but percentage of inhibition bolth of isolate ware not significantly different at 5% level test results.
