How should pests and diseases of passion fruit be handled? Do you know? Let us take a look together.

Recommendations: Testing found no occurrence of pathogenic bacteria or insect bodies; based on the pattern of damage, it is judged that this may be related to cultivation management. Please note whether the abnormality was found within 3 days after applying the product; if so, it is very likely related to the materials applied before the occurrence.
