Abstract
Trichoderma harzianum 23 WP and Bacillus subtilis 122 WP were formulated as antagonists of Sclerotium cepivorum and Sclerotium sp. of garlic white rot. In the field test, applications of Trichoderma harzianum WP and Bacillus subtilis WP reduced garlic white rot by Sclerotium cepivrum from 10.9% in the control to 4.1% and 6.2%, respectively at Taean. Also at Seosan, applications of Trichoderma harzianum 23 WP and Bacillus subtilis 122 WP reduced garlic white rot by Sclerotium sp. from 17.8% in the control to 1.2% and 2.6%, respectively. Treatment of Trichoderma harzianum 23 WP and Bacillus subtilis 122 WP increased garlic yield in two area. Therefore, Trichoderma harzianum 23 WP and Bacillus subtilis 122 WP have shown potential as biofungicides of garlic white rot in the two different pathogens.
