It works as an insect growth regulator (inhibits moulting) while also affecting the insect's nervous system by blocking message transmission via acetyl choline disruption leading to paralysis and death of the insect.
Unione, used as an early season spray, can be a more efficient, long-lasting, and effective method for BPH and WBPH control in rice.
