IRRI ON LEAF FOLDER:- http://www.knowledgebank.irri.org/tra... Why is it important The damage caused by leaffolders may be important when it affects more than half of the flag leaf and the next two youngest leaves in each tiller. At vegetative phase, crops can generally recover from damage; but when leaffolders infest at reproductive phase, the damage can be economically important. High feeding damage on the flag leaves can cause yield loss. Most early season insecticide use have little or no economic returns. Instead, it can cause ecological disruptions in natural biological control processes, thus enhancing the development of secondary pests, such as planthoppers. PAU ON LEAF FOLDER:- Leaf folder: The larvae fold the leaves, eat out the green tissue and produce whitestreaks (Plate No. 4, page 186). The damage is highest during August-October. When the leaf damage reaches 10% (ETL), adopt the following control measures: • Mechanical Control: The mechanical control of leaf folder can be done only before flowering by passing the 20-30 m long coir/jute rope, forwards and then backwards, both ways while touching the crop canopy. While passing the rope, ensure that water must be standing in the crop. • Chemical Control: Spray the crop 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/Durmet/Force 20 EC (chlorpyriphos) or 80 ml neem based bio-pesticide, Ecotin (azadirachtin 5%) in 100 litres of water per acre. Prefer Ecotin at pest initiation stage.
