Viability and role of Beauveria Bassiana as endofit in Corn Bima 11 Tammu Tammu varieties against Aphids sp.

Abstract

Abstract Corn production can be increased by the use of superior varieties both free-range (non-hybrid) and hybrid corn. Hybrid corn can produce higher yields compared to free-roasted corn. Bima-11 Tammu Tammu variety is corn seed from the breeding of B11-126 (female), Mr-15 (male) varieties. One of the pests commonly found in corn plantations is aphids Aphids spp. One of the control alternatives that can be used is applying the entomopathogenic of Beauveria bassiana . The effectiveness of B. bassiana as a control for a number of insect pests has been proven. Damage due to Aphids sp. can be more severe, because these pests can transmit viral diseases to corn plants. This research begins with the preparation of Bima 11 Tammu Tammu varieties, seed viability test, preparation B. bassiana , re-isolation of plant tissue to detect the presence of B. bassiana , and Preparation of Aphids sp. The results showed that endophytic seeds had high viability and B. bassiana as endophytes in corn plants, application of B. bassiana to corn plants proves that it appears that the presence of B. bassiana in corn plants is three weeks after application, and Aphids sp. mortality in endophytic corn plants and in corn plants sprayed with B. bassiana is no different.
