Application of thermostable chitinase I168L in the control of anthracnose on avocado and evaluation of cross-infection ability of Colletotrichum species

Key Points

• Chitinase I168L effectively reduces anthracnose severity in avocado plants and mitigates disease spread.
• The treatment resulted in a significant reduction of infection rates, achieving a decrease of up to 70% in affected fruit.
• Application involved evaluating the cross-infection ability of various Colletotrichum species across treated plants.
• Further validation in field settings is needed to confirm these laboratory findings and address potential limitations.
