SEMPRA, being a sulfonylurea group herbicide, inhibits acetolactate synthase (ALS), which is the first enzyme in the biosynthetic pathway of the essential branched chain amino acide (Valine, Leucine & isoleucine). Inhibition of ALS leads to the starvation of the plant (Cyperus rotundus) for these amino acids, resulting in death (killing) of weeds. For crop plants, in the grass family like maize sugarcane, etc. there is no effect of Sempra as these plant have strong MFO (mixed function oxidases which breaks down the herbicide molecule to acid metabolite forms.
Carbomain is a systemic carbamate insecticide/ nematicide, effective against a wide range of insect pests on all major agricultural crops.
Carbomain formulation have demonstrated effective pest control both by contact and systemic action.
Carbomain is absorbed by the plant roots when applied the soil and moves systemically via the vascular system to control root feeding as well as foliar pests. Foliar applications control insects through direct contact and ingestion of treated plant parts.
