Streptomyces Lydicus Shelf Life and Storage for Citrus

Streptomyces lydicus is a living microbial biofungicide. Unlike conventional chemical products, it contains beneficial microorganisms whose effectiveness depends on maintaining high viability from manufacturing until field application. Proper storage, transportation, and handling are therefore critical for achieving consistent results in citrus production.

Although the exact shelf life varies by manufacturer and formulation, most quality Streptomyces lydicus products are designed to remain stable for 12–24 months when stored according to the label instructions. Always rely on the expiry date and storage recommendations provided by the manufacturer.

Recommended Storage Conditions

For maximum microbial survival:

• Store in a cool, dry place.
• Protect from direct sunlight.
• Keep away from excessive heat.
• Avoid freezing unless specifically recommended.
• Keep containers tightly sealed after opening.
• Store in the original packaging.
• Protect from rain and moisture.

Maintaining stable storage conditions helps preserve microbial viability throughout the product's shelf life.

Ideal Storage Temperature

Most microbial biofungicides perform best when stored at temperatures recommended by the manufacturer, commonly between:

• 15°C and 25°C for many dry formulations.
• Some formulations may tolerate wider temperature ranges.

Avoid prolonged exposure to temperatures above 35°C, especially during transportation and warehouse storage, as excessive heat can reduce the viability of living microorganisms.

Transportation Guidelines

During transport:

• Avoid leaving products inside parked vehicles under direct sunlight.
• Prevent prolonged exposure to high temperatures.
• Protect packaging from water damage.
• Minimize physical damage to the containers.

Proper logistics are especially important during hot summer months.

Handling After Opening

Once opened:

• Reseal the package immediately after use.
• Prevent moisture from entering the container.
• Use clean, dry measuring equipment.
• Avoid contaminating the remaining product.
• Use the remaining product within the manufacturer's recommended period after opening.

Water Quality During Application

To protect microbial viability:

• Use clean water.
• Avoid highly chlorinated water whenever possible.
• Maintain suitable water pH according to label recommendations.
• Prepare spray or drench solutions immediately before application.

Long storage of mixed solutions is generally not recommended unless specifically stated by the manufacturer.

Signs of Improper Storage

Products may have reduced microbial viability if they have been:

• Stored in excessive heat.
• Exposed to repeated moisture.
• Kept beyond the expiry date.
• Stored in damaged or open packaging for extended periods.

When in doubt, consult the manufacturer before use.

Suitable for All Citrus Crops

Properly stored Streptomyces lydicus products are suitable for:

• Orange
• Lemon
• Mandarin
• Sweet Lime (Mosambi)
• Lime
• Grapefruit
• Pomelo

Whether used in nurseries, young orchards, mature plantations, or high-density citrus systems, maintaining product quality before application is essential for achieving successful microbial establishment in the root zone.

Best Storage Practices

For the best field performance:

• Purchase products from authorized suppliers.
• Check manufacturing and expiry dates before use.
• Store under recommended conditions immediately after purchase.
• Transport carefully during hot weather.
• Follow label instructions for storage, mixing, and application.
• Rotate stock using the "first in, first out" (FIFO) principle.

By protecting the viability of beneficial microorganisms throughout storage and handling, citrus growers can maximize the biological performance of Streptomyces lydicus and maintain a healthy rhizosphere throughout the growing season.
