ABSTRACT
So far, many farmers still use chemical pesticides and fungicides for their crops. This makes the
plants produced contain a number of chemicals that are not good for health. Pathogenic fungi can be
avoided by using fungicides from natural ingredients instead of chemical fungicides. One disease
that is often found in red chili plants (Capsicum annum) is fusarium wilt. Previous studies have
stated that the use of Trichoderma can reduce the wilting rate due to Fusarium. However, no studies
have compared the ability of Trichoderma to Fusarium from various locations. Because of this, in
this study a comparison of the antagonistic abilities of Trichoderma originating from three cities,
namely Bandung, Tasikmalaya, and Banjar, will be carried out against Fusarium. The
implementation method used is by inoculating Trichoderma with Fusarium in one petri dish. Then
the diameter of the growing Trichoderma and Fusarium colonies was measured. Then an analysis
was carried out by measuring the percentage of inhibition value of Trichoderma against Fusarium.
The PIRG results showed that Trichoderma from Banjar had better results than Trichoderma from
Tasik and Lembang. This is due to changes in metabolite results or due to differences in subcultures.
Trichoderma affects the inhibition of Fusarium growth. The higher the value of the length and width
of Trichoderma, the lower the value of the length and width of Fusarium because its growth is
inhibited by the growth of Trichoderma.
