Principle of action:
Imidacloprid has pronounced systemic and contact activity, penetrates into plants through leaves and stems. The substance actively affects the nervous system of harmful insects, blocking the nicotinic receptors of the postsynaptic nerve, and quickly inhibits the transmission of signals through the central nervous system of pests, as a result of which they first lose movement activity and stop feeding. Lambda-cyhalothrin disrupts the function of the nervous system, acting on the exchange of calcium in synapses and sodium-potassium channels. Poisoning manifests itself in damage to the motor centers and in strong excitement. Provides quick destruction of pests. Additionally, it acts against the larvae and adults of ticks, suppresses their development, preventing their number from growing.
