UJI BEBERAPA DOSIS BIOFUNGISIDA BERBAHAN AKTIF Trichoderma koningii Rifai TERHADAP PENYAKIT VIRUS KOMPLEKS, PERTUMBUHAN DAN PRODUKSI CABAI MERAH (Capsicum annuum L.)
Abstract: One of the disease
that can significatly decrease the red chili productivity is virus complex. The
disease can be controlled by the utilization of microorganism such as
Trichoderma koningii Rifai formulated in a biofungicide. The dose of
biofungicide given to the plants can determine the effect of virus complex
disease. The research aims to obtain the best dose of biofungicide of T. koningii to increase the resistance of
red chili to virus komplex and to study its effect on the growth and yield of
the red chili. This research has been conducted at Plant Pathology Laboratory
and Agribusiness Incubator Green House, Agriculture Faculty of Riau University
from October 2015 to February 2016. The research was carried out experimentally
using a completely randomized design consisted of 5 doses (0, 25, 50, 75 dan
100 g/polybag) and 3 replication. Data obtained were statistically analyzed
using analysis of variance and continued with Duncan’s New Multiple Range Test
(DNMRT) at 5% level. The result showed that the virus complex infection in red
chili which were applied with some doses of biofungicide of T. koningii had
different effect on the first time of symptom appeared, disease intensity,
plant growth and yield. Biofungicide of T. koningii at 100 g/polybag can increase
the resistance of red chili and the growth and production.
