Frequently Asked Questions (FAQs)

Q1: What makes NUCLEAR 505 different from single-ingredient insecticides?
A1: It combines Chlorpyriphos (longer residual control) with Cypermethrin (rapid knockdown) to control a broader pest complex with both immediate and lasting effects.

Q2: Can I tank-mix NUCLEAR 505 with other pesticides?
A2: Many tank mixes are possible, but always perform a jar test before large-scale mixing and follow label recommendations to avoid antagonism or crop injury.

Q3: What safety precautions should be taken during application?
A3: Wear protective clothing, gloves, and a mask; avoid inhalation and contact with skin; do not spray near water bodies and follow buffer zone guidance on the label.

Q4: What is the expected residual activity on cotton?
A4: Residual activity varies with weather and crop conditions; when applied correctly, Chlorpyriphos component provides extended residual control while Cypermethrin gives immediate knockdown.
