FAQ for Ratna Nova Star
How does Novaluron in Ratna Nova Star work?
Novaluron inhibits chitin synthetase enzyme in insects, preventing proper new cuticle formation during molting. Affected larvae die during attempted ecdysis unable to shed their old cuticle.
Which crops is Ratna Nova Star recommended for?
Ratna Nova Star is recommended for cotton, cabbage, tomato, chilli, and Bengal gram for control of American bollworm, DBM, fruit borers, tobacco caterpillars, and pod borers.
At what stage should Ratna Nova Star be applied?
Apply Ratna Nova Star targeting young early instar larvae before they penetrate into fruits, bolls, or pods. Chitin inhibitors are most effective and economical against early larval stages.
Is Ratna Nova Star effective against diamond back moth (DBM)?
Yes, Ratna Nova Star is highly effective against DBM on cabbage — including populations resistant to pyrethroids and organophosphates — due to Novaluron's unique chitin inhibitor mode of action.
Can Ratna Nova Star be used in rotation programs?
Yes, Novaluron's chitin synthesis inhibitor mode of action is distinct from other insecticide classes, making Ratna Nova Star an ideal rotation partner for resistance management programs.
