Apply horticultural oil or neem spray early in the season and prune any infested branches to eliminate larvae. Ensure adequate plant spacing and air flow to lower humidity, which suppresses tick development.
How to fight ticks in currants? - in detail
Effective control of tick infestations on currant bushes requires an integrated approach that combines cultural, mechanical, biological, and chemical measures.
First, maintain proper orchard hygiene. Remove fallen leaves, fruit, and debris each season to eliminate shelters where ticks develop. Prune vines regularly to improve air circulation and sunlight penetration, conditions that reduce tick survival rates.
Second, implement physical barriers. Install fine mesh netting or row covers over young plants during peak tick activity periods (late spring to early summer). Ensure the material has openings no larger than 0.5 mm to prevent adult ticks from reaching foliage.
Third, encourage natural enemies. Plant companion species such as rosemary, thyme, and sage, which attract predatory insects (e.g., predatory mites and parasitic wasps) that feed on tick larvae. Avoid broad‑spectrum insecticides that would harm these beneficial organisms.
Fourth, apply targeted acaricides only when monitoring indicates population thresholds are exceeded. Use products containing spinosad, abamectin, or neem oil, following label directions for dosage, timing, and re‑application intervals. Rotate active ingredients to delay resistance development.
Fifth, monitor regularly. Conduct weekly inspections by examining leaves, stems, and fruit for tick presence. Use a hand lens to identify all life stages. Record counts and compare them with established economic injury levels to decide whether intervention is warranted.
Finally, practice sanitation after harvest. Collect and destroy all dropped fruit and plant material, then compost at temperatures above 60 °C to kill residual ticks. Rotate planting sites or intersperse currants with non‑host species to break the life cycle.
By integrating these steps—sanitation, barriers, biological allies, judicious chemical use, systematic scouting, and post‑harvest cleanup—growers can suppress tick populations on currant crops while minimizing environmental impact and preserving plant health.
