Chlorybria
The widest pest label in the range — scales, borers, aphids, soil pests and leafworms.
Chlorybria is a high-load organophosphate insecticide based on chlorpyrifos-ethyl at 480 g/l. Its registered pest list is the longest of any product Sembria carries — more than thirty targets across fruit, olive, vine, sugar beet, vegetables, cereals, cotton, corn and pistachio. It is particularly valued where softer chemistry struggles: armoured scale insects under a waxy shield, wood-boring larvae inside the trunk, and soil-dwelling pests such as wireworms and springtails.
Characteristics
- The broadest pest spectrum in the Sembria insecticide portfolio
- Effective on armoured and soft scale insects that resist contact-only products
- Controls wood-boring larvae, soil pests and the full aphid complex
- Registered for both summer and winter (dormant) control programmes on fruit
- Contact, stomach and vapour activity
- High active loading at 480 g/l — low volume per hectare
How it works
Chlorpyrifos-ethyl inhibits acetylcholinesterase at the nerve synapse. Acetylcholine accumulates, nerve firing becomes continuous, and the insect dies of convulsive paralysis. The vapour phase reaches pests under bark and beneath scale covers. IRAC Group 1B.
