There was strong suppression of adult formation 65 and 91% at 25 and 50 mg L −1, respectively. 1st-instar larvae were the most susceptible developmental stage. Larvae that hatched from treated eggs were significantly affected at concentrations of 25 ppm and higher. The results showed that egg hatch was affected by high concentrations (50 and 100 ppm) of the tested compounds. The effects of these compounds on some biological aspects of the black cutworm, Agrotis ipsilon, and their field persistence residues were estimated. Emamectin benzoate, indoxacarb and chlorantraniliprole are broad-spectrum insecticides with a novel mode of actions. Still, there is an ongoing need to replace older conventional insecticides with new insecticides to maintain efficacy and environmental protection. For detailed instructions on application techniques, download the technical sheet or consult your Bioline advisor for more information.Chemical control is used as a rapid and reliable method for insect control.Do not exceed a pump pressure of 20 bar/ 300psi, for Dosatron 6 bar/ 100psi.Keep nematode solution agitated continuously alternatively add carboxy-methyl cellulose (wallpaper paste) at 0.4% w/v to prevent nematodes settling, mixture should still be used within 4 hours.Use nozzles with at least 0.8 mm diameter. Remove all fine filters in the tubing and at the nozzles.The entire spray solution should be applied once mixed.
For optimum results, keep the soil moist for 3-4 weeks after application.For drench applications over foliage use lower volumes of water and irrigate within 30 minutes of treatment with at least 1 litre/ m2 to wash nematodes off the leaves and below the soil surface.Apply with at least 4 litres / m2 water if applied direct to soil.
Apply early morning or late evening to minimize the effect of heat and sunlight.
