Iron Deficiency - Cotton

Should that be considered as iron deficiency ? If so , can I spray micronutrients with insecticides ?

Want to know whether I can spray micronutrients combined with insecticides.

Hello, Iron Deficiency . spray chelated ferrous sulphate 2 gms in 1litre of water. it can be mixed with insecticide s. but, no insects damage is seen.

latest status. Problem seems to be cleared but , leaves lost their lively color. Turning into pale and curling upwards. Local guys said , it's due to insects. Can anyone suggest a best insecticide ?

sHi chaitu, i have suggested to spray chelated ferrous sulphate plus systemic insecticide. please confirm what you have sprayed.i want common name. OK?

UpvoteDownvote
C

couldn't get specific ferrous sulphate. so , used all mineral mixture with 4% iron , manganese , copper , molybdenum e.t.c... used fipronil 5% as insecticide. ( wasn't sure about it's efficiency ).

C

common name of mineral mixtue is swarnaphal , and insecticide is rhymegent

M

Ok, mineral mixture and fipronil spray will ease your tension.
