Chlorpyrifos 50% EC is used to control Termites in Buildings, during construction and in existing buildings and bollworm in cotton crops. *Caution : Toxic to aquatic organisms hence should not be used near water bodies, aquaculture or pisciculture. It is toxic to honeybees, spray application should be avoided during foraging period of bees. Product is highly toxic to birds hence avoid use near bird habitat. 1. EQUIPMENT USED IN APPLICATION:Knapsack sprayer, Knapsack power sprayer, motorized Knapsack sprayer cum duster, compression Knapsack sprayer, compression Knapsack battery sprayer, wheel barrow sprayer and HTP power sprayer. 2. For Termite control - Methods of application and equipment for use : 1. During construction : Mix 1 Ltr. of chlorpyrifos 50% EC with 99 L of water to get a 0.5% chlorpyrifos emulsion and apply at the following stages. Satge 1 - Treat the bottom surface and sides (upto 30cm. Height) of the excavations made for column pits, wall trenches and basements @ 5L per sq. m of surface area. Stage 2 - Treat the refill. Earth on both sides of all built up walls (approximately width 30cm and depth 45cm) @ 7.5 per sq.m of substructure. Stage 3 - Treat the entire levelled surface (before laying the floor) @ 5L per sq.m In case of RCC framed structures with columns and plinth beams and RC basements, the treatment can start at a depth of 50cm, below ground level. Wherever pipes, wastes and conduits enter soil, loosen the soil for a distance of 15cm. And 7.5cm deep and thoroughly drench with chlorpyriphos 50% EC emulsion. Note:All applications should be done when the surface is dry to facilitate better absorption. Treatment of existing build i) Dig shovel width trenches along the external wall of the building exposing the foundation wall surfaces upto a depth of 50 cm. And made 30 cm-50cm, deep rod holes. 15 cm apart all along this trench and pour Chlorpyriphos 50% Ec emulsion @1.75 litrs per running meter. ii) treat the back fill each with earth Chlorpyrifos 50% EC emulsion @ 0.5 L per running meter as it is returned to the trench directing the spray towards the wall surface. PS- If there is concrete or masonry apron around the building, drill 12mm holes as close as possible to the plinth wall 30 cm apart and pump insecticides.. A) RCC framed Structures: Excavate shovel width trenches exposing the sides of the column and plinth beams upto 30 cm. (or bottom of the plinth beams) and treat the back fill earth with Chlorpyrifos 50% emulsion as it is returned to the trench, @ 7.5 L per sq.m of the vertical surface of the structure. B) Internal treatment (Soil under floors): Soil below any openings of the floor is to be charged with the chemical so as to deny access to termites.
