Streptomyces Lydicus After Harvest in Mango

The period immediately after harvest is one of the most important stages in mango orchard management. After producing fruit, mango trees begin rebuilding carbohydrate reserves, regenerating feeder roots, and preparing for the next flowering cycle. Healthy root development during this period determines how effectively the tree can absorb nutrients and recover before the following season. Streptomyces lydicus is a beneficial soil bacterium and biological biofungicide that helps establish a healthy rhizosphere during this critical recovery phase.

Following harvest, many mango trees produce a fresh flush of feeder roots. Applying Streptomyces lydicus through soil drenching, drip irrigation, or fertigation allows the beneficial microorganism to colonize these actively growing roots. Once established, it competes with harmful fungi for nutrients and root colonization sites while producing naturally occurring antimicrobial compounds that help suppress soil-borne pathogens including Fusarium, Rhizoctonia, Pythium, and Phytophthora.

Healthy feeder roots absorb nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, zinc, boron, iron, and other essential nutrients required for rebuilding tree reserves after harvest. Improved nutrient uptake supports new vegetative growth, stronger shoot development, healthier leaves, and improved carbohydrate storage that contributes to more uniform flowering and fruit set in the following production season. A biologically active root zone also improves fertilizer use efficiency and promotes long-term orchard productivity.

Post-harvest biological management should be integrated with orchard sanitation, pruning, irrigation management, and balanced fertilization. Removing diseased plant debris, pruning damaged branches, improving soil aeration, and incorporating organic matter create favorable conditions for beneficial microorganisms to establish. Streptomyces lydicus performs exceptionally well when used together with Trichoderma, Bacillus subtilis, Bacillus velezensis, Pseudomonas fluorescens, Azotobacter, phosphate-solubilizing bacteria (PSB), potassium mobilizing bacteria (KMB), zinc-solubilizing bacteria, mycorrhizal fungi, compost, vermicompost, and well-decomposed farmyard manure.

Commercial mango growers increasingly include Streptomyces lydicus in post-harvest orchard management because healthy roots developed during this period directly influence the next crop cycle. By improving soil biology, protecting feeder roots, enhancing nutrient uptake, and supporting beneficial microbial populations, Streptomyces lydicus helps maintain healthier orchards, improves long-term productivity, and supports sustainable mango cultivation in conventional, integrated, organic, and regenerative farming systems.
