Abstract

Anthracnose disease in chili is caused by C. acutatum. This disease can cause a decrease in quality and production of chili pepper. The use of biological control agents can be an alternative in controlling of C. acutatum. The use of biological agents is more environmentally friendly and reduces the negative effects of synthetic pesticides. This study aims to obtain yeast isolates from the phyllosphere that have the potential to suppress anthracnose disease. The research was carried out at the Laboratory of Diseases at the Faculty of Agriculture, Tanjungpura University, Pontianak from July to October 2019. Yeast isolation used a pouring plate method on the media YGCA after the yeast on the fruit surface was enriched in liquid media YGC during 24 hours. Yeast antagonism test against C. acutatum using the dual culture method, conidia viability, and the ability of pathogens to infect fruit. The results of the isolation obtained 8 yeast isolates in healthy chili of Gada variety. Antagonism test obtained 3 yeast isolates with the highest inhibitory to C. acutatum growth, isolates K2, K3 and K5. Inhibition is greater than 50%. Based on the severity index of the disease in the hypovirulent test, the three yeast isolates were not pathogenic. In the in vivo test with the immersion method, both using yeast cells and filtrate showed that yeast cells could inhibit the growth of C. acutatum infection ability better than yeast filtrate. All yeast isolates can suppress the growth of C. acutatum with a different percentage of disease.

Abstract

The West Kalimantan land is mostly dominated by marginal peat land types. The West Kalimantan peat swamp land has a very low pH, low nutrient availability, low base saturation, high nutrient washing rates, and even some of them are sandy soil which is in the lower layers. One way to utilize peat marginal land as an agricultural crop is by utilizing Arbuscular Mycorrhizal Fungi (FMA) as biological fertilizer inoculums. The stages of the research are the exploration of FMA from several root zone plants from two locations, Galang and Rasau Jaya Villages, then identification of FMA in the plant disease laboratory of Tanjungpura University's Faculty of Agriculture. The study was carried out for ± 3 months. The design used is by using purposive sampling method, with the number of sample points on three commodities, namely pineapple, fern and grass, each of 9 sample points. The results showed an analysis of the content of the number of FMA spores found in the highest root rooting zone found in the source of pineapple inoculums, with the number of FMA spores found as many as 96, with soil samples each of 50 g samples. Whereas the fern media amounted to 55, and the grass media amounted to 22. The highest level of FMA diversity was found in the treatment with the source of pineapple inoculum from Galang, with the discovery of three types of FMA namely genus Glomus sp, Gigaspora sp and Acaulospora sp. Keywords: arbuscular mycorrhizal fungi (AMF), exploration, marginal peat soi
