Managing Mite Infestations with Nissorun WP

Dealing with spider mites on fruit trees or soybeans requires a precise, long-lasting solution. From an operator’s perspective, Nissorun WP, produced by the Japanese company Nippon Soda Co., stands out due to its unique ability to disrupt the mite life cycle rather than just providing a temporary knock-down effect.

Application and Field Observations

As a wettable powder, proper preparation of the tank mix is essential. I always recommend creating a concentrated pre-mix before filling the main tank to ensure the powder is fully suspended, preventing any nozzle clogging. Since this is a contact-type acaricide, the quality of your spray coverage is everything. You must ensure thorough coverage of both sides of the leaf, especially the undersides where the red and brown fruit mites reside.

• Operational Strategy: The label allows for only one application per season. This makes timing critical—you need to catch the early stages of infestation to prevent economic damage.
• Efficiency: The product effectively controls eggs, larvae, and nymphs, preventing the next generation from maturing.
• Safety and Logistics: Classified under toxicity class 3, handling Nissorun is straightforward with standard PPE. However, always keep the 30–45 day pre-harvest interval in mind when planning your spray schedule for grapes, strawberries, or apples.

The biggest advantage for the grower is the residual activity. After a single application, the pressure from mites drops significantly and remains low for an extended period. This provides the crop with the necessary stability to recover its photosynthetic capacity without constant re-spraying, making it a reliable tool for high-value agricultural production.
