How to Treat Durian Canker Organically with BSF Fertiliser

Durian canker (Phytophthora palmivora) is the #1 disease threatening Malaysian durian farms. This guide shows how M-PLUS Bio BSF organic fertiliser helps prevent and treat canker without chemical fungicides.

What is Durian Canker?

Durian canker is caused by the soil-borne pathogen Phytophthora palmivora. It attacks the trunk, branches, and roots, causing brown lesions, gum exudate, and eventual tree death if untreated.

Why BSF Organic Fertiliser Helps

M-PLUS Bio BSF fertiliser contains beneficial microorganisms that suppress Phytophthora in the rhizosphere. The chitin from BSF exoskeleton stimulates the plant's natural defence system (SAR — Systemic Acquired Resistance).

Step-by-Step Treatment Protocol

1. Scrape off infected bark and apply Bordeaux paste to the wound
2. Apply M-PLUS Bio BSF fertiliser (500g per tree) around the drip line
3. Water thoroughly to activate soil microbiome
4. Repeat monthly for 3 months during active canker season
5. Monitor for new lesions and reapply as needed

Results: Farms using M-PLUS Bio BSF fertiliser report 60–80% reduction in canker incidence within one growing season.
