| Ha | Acre... | |||||
| acetamiprid (Assail) 27128 | 4 | 80-120 g | 32-48 g | 12 h-6 days | 7 | Do not apply more than twice per season alone or alternately with Admire. Spray interval - 12 days. REIs of 2 days for scouting and 6 days is for thinning. |
| abamectin (Agri-Mek SC) 31607 | 6 | 170 mL | 69 mL | dry | 28 | Apply with 0.25% superior oil. Do not apply more than once/season. Will also control rust mites and leafminer larvae. Residual control: 21 days. |
| methoxyfenozide (Intrepid) 27786 | 18 | 500 mL | 200 mL | 12 h | 14 | Apply at first egg hatch of first generation.Spray interval: 14 to 21 days. |
| spinetoram (Delegate) 28778 | 5 | 210-420 g | 85-170 g | 12 h | 7 | Apply at egg hatch or first sign of sap-feeder larvae. Do not apply more than 3 times per season. use higher rate under high pest pressure. Spray interval: 7 days. |
| abamectin + cyantraniliprole (Minecto Pro) 33023 | 6 + 28 | 496 mL | 201 mL | 12 h | 28 | Apply against egg (to control new hatch) and early sap feeder stages of first and second generation tentiform leafminers when locally established thresholds have been reached. Add 0.25 - 1% spray oil/ spray mixture. Also controls leafroller and mites. Maximum 1 application per season. |
| acetamiprid + novaluron (Cormoran) 33353 | 4 + 15 | 700 ml | 283 | 12 hrs to 7 days | 14 days | Do not apply more than 6.9 L/ha. Spray interval - 12 days. REIs: 7 days for thinning, 12 hours for all other activities. |
| Notes: The leafminer parasite is an effective biological control agent. 30% parasitism of first generation tissue-feeder larvae in the spring will provide control of leafminers for the rest of the season. If chemical control is needed rotate products for resistance management. Avoid using Group 4 products more than twice/season for all registered uses to prevent mite problems. | ||||||
