How to use phytoverm against spider mite? - briefly
«Apply Phytoverm as a foliar spray at the recommended concentration, ensuring complete coverage of both leaf surfaces, and repeat applications every 7‑10 days until mite numbers drop.» «Avoid extreme temperatures and direct sunlight during treatment to preserve product efficacy.»
How to use phytoverm against spider mite? - in detail
Spider mites damage crops by feeding on leaf tissue, causing chlorosis and reduced yield. Phytoverm, a systemic acaricide containing abamectin, provides rapid control when applied correctly.
Effective use requires precise preparation and timing. Follow these steps:
- Dissolve the recommended amount of product in clean water, typically 2 ml per litre for a 0.2 % solution; adjust according to label instructions and infestation severity.
- Stir the mixture until fully homogenised; avoid vigorous shaking that may introduce foam.
- Apply the solution as a fine spray to the underside of leaves, ensuring complete coverage of foliage and stems where mites congregate.
- Conduct the first treatment early in the morning or late afternoon to minimise photodegradation and reduce plant stress.
- Repeat applications at 7‑day intervals until mite populations decline below economic thresholds; do not exceed the maximum number of applications listed on the label.
Key considerations:
- Temperature should remain between 10 °C and 30 °C during application; extreme heat can reduce efficacy.
- Rainfall exceeding 2 mm within 24 hours after spraying can wash off the product, necessitating re‑application.
- Avoid mixing Phytoverm with oil‑based surfactants, which may antagonise its mode of action.
- Observe pre‑harvest intervals and residue limits for specific crops to ensure compliance with safety regulations.
Resistance management strategies include rotating Phytoverm with acaricides of different chemical classes and integrating biological controls such as predatory mites. Monitoring mite counts two days after each application helps assess treatment success and informs subsequent decisions.
