Rice stem borer attack 45 to 55 days (ਖਾਦ ਬੰਦ ਹੋ ਗਈ, ਗੋਭ ਸੁੱਕ ਰਹੇ ਹਨ , ਸੁੰਡੀ ਮਰ ਨਹੀ ਰਹੀ ਕੀ ਕਰੀਏ) 

Rice stem borers: The larvae of these insects bore into the stem and cause damage from July to October. The affected young plants show dead-hearts (yellowing and drying of central shoot) whereas the old ones produce empty earheads which turn white and stand erect
The fields showing more than 5% dead hearts (Economic Threshold Level, ETL) should be sprayed with 60 ml Coragen 18.5 SC (chlorantraniliprole*) or 20 ml Fame 480 SC (flubendiamide* 39.35%) or 50 g Takumi 20 WG (flubendiamide* 20%) or 170 g Mortar 75 SG (cartap hydrochloride) or 1 litre Coroban/Dursban/Lethal/Chlorguard/Durmet/Classic/ Force 20 EC (chlorpyriphos) or 80 ml neem based bio-pesticide, Ecotin (azadirachtin 5%) in 100 litres of water per acre. Further application of any of these insecticides may be repeated as and when damage reaches economic threshold level. Prefer Ecotin at pest initiation stage
