Applicaton:
Application timing varies by target pest. For codling moth in apples, spray according to forecast/warning systems targeting larval emergence . For Sunn pest in cereals, apply when pests fall into fields . For cereal weevil, spray 10 days after stem rising period . For cotton bollworm in cotton/tomato, begin treatment when 5/100 plants are infested . For corn borer in corn, start at first egg detection followed by 2-3 applications at 15-day intervals . For mosquito control (public health), ULV spatial application at 500 mL/ha provides 100% mortality
Application methods include ground spray (foliar broadcast/row treatment), aerial application, and ultra-low volume (ULV) spraying . For row treatment of cutworms, use 0.2 mL per 100 m row . Thorough coverage is essential for optimal control. Application rates: corn stalk borer at 100-125 mL/ha, cotton bollworm at 100-200 mL/ha, olive fruit fly at 25 mL/100 L water, codling moth at 20 mL/100 L water .
Alpha-cypermethrin is highly toxic to bees, fish, and aquatic organisms — avoid application during flowering periods and keep away from water bodies . The preharvest interval (PHI) is typically 7-14 days depending on crop . For cotton, apply no more than 3 times per season with a 14-day PHI . Do not mix with alkaline pesticides .
Cautions:
Toxicity to Non-Target Organisms: Alpha-cypermethrin is highly toxic to bees, fish, aquatic organisms, and silkworms . Avoid application during flowering periods of crops, near apiaries, sericulture areas, or fish ponds . Do not contaminate water bodies or clean application equipment in or near water sources .
Do Not Mix with Alkaline Substances: This product is incompatible with alkaline pesticides (e.g., Bordeaux mixture, lime sulfur) and alkaline water sources, as high pH causes decomposition and loss of efficacy . Do not mix with alkaline materials .
Resistance Management: To delay the development of resistance, rotate Alpha-cypermethrin (IRAC Group 3 – sodium channel modulators) with insecticides from different chemical classes that have different modes of action .
Precaution for Sensitive Individuals: Pregnant or breastfeeding women should avoid handling or exposure to this product .
