Eucalyptus leaf aqueous extract - a promising biopesticide for managing bacterial spot disease in tomato plants.

Summary: Plant diseases are a big threat to our food supply, and farmers often rely on harsh chemicals to fight them. But what if a natural leaf could help? Scientists tested a water-based extract made from Eucalyptus leaves on tomato plants infected with a harmful bacteria called bacterial spot disease. They found that soaking infected tomato seeds in the Eucalyptus extract helped them grow longer roots and show fewer signs of sickness. When sprayed on older plants, the extract lowered the number of bacteria and reduced disease symptoms over three weeks. This means Eucalyptus leaves could be a great, eco-friendly alternative to chemical pesticides for keeping our crops healthy!
