Use Patterns and Formulations Application sites: apples, pears, grapes, apricots, melons, cantaloupes, cucumbers, peaches, pumpkins, raspberries, squash, nursery stock, orna- mentals, and home gardens. Types of formulations: liquid, wettable powder, dust, aerosol Types and methods of application: ground boom, mist blower, airblast, handheld sprayers Application rates: rate and frequency vary according to site application ------- -2- 3• Science Findings: Physical,and Chemical Properties Color Boiling Point — Solubility — Appearance at room temperature Dark reddish-brown 138 to 140°C Soluble in most organic solvents, but almost insolu- ble in water White, crystalline solid at 23°C Tolerance Assessment? Tolerances were established in 4 0 CFR 180.341 for residues of dinocap Toxicology Summary: ¦¦ -*¦ ; Acute toxicity - For technical dinocap, the acute oral LD50 in rats is §80 rag/kg. Chronic Toxicity - Dinocap produces developmentally toxic effects in rabbits. For oral exposure, the NOEL for these effects is .5 mg/kg/day; for dermal exposure, the NOEL is 50 mg/kg/day. 4. Summary of Proposed Regulatory Position The Agency is propos ing that current registrat ions for the use of dinocap on agricultura.1 and nonfood crops will be allowed to cont.inue provided the following conditions and label modifications are met to reduce applicator exposure: 1. require ground boom, airblast and mist blower equipment to be drawn by enclosed vehicles 2. reclassify as a restricted use pest ic ide requiring the physical presence of the certified applicator 3. require use of a developmental toxicity warning on the label: "Use of this product may be hazardous to your health. This product has been determined to cause birth defects in laboratory animals." 4. require use of water-soluble packaging for wettable powder formulations 5.
