Bonide® All Seasons® Horticultural & Dormant Spray Oil

Bonide® All Seasons® Horticultural & Dormant Spray Oil earns its name — a single product that delivers two distinct applications across the full growing calendar. In winter and early spring, use it as a dormant oil to smother overwintering pest eggs and larvae before they hatch into this year’s problem. During the growing season, use it for contact control of active infestations of scale, mites, and aphids. It also controls fungal diseases including powdery mildew and rust. A natural paraffinic (mineral) oil that works without synthetic chemistry — effective on fruit trees, shade trees, flowering trees, roses, vegetables, and other garden plants.

Two Applications — One Trusted Product

Most pest control products are designed for either dormant application or growing season use. Bonide® All Seasons® does both. The dormant and early spring application proactively targets overwintering scale, mite, and aphid eggs and larvae before the season begins — interrupting pest cycles at their most vulnerable point. The growing season application provides contact control of active infestations on the same broad range of plants. That dual utility makes All Seasons® one of the most versatile and practical products in any home orchard program.

Broad Coverage — Insects, Mites, and Fungal Disease

The pest and disease coverage is comprehensive. Scale, mites, and aphids — from eggs through larvae and adults — are the primary targets, but the oil also controls some fungal diseases including powdery mildew and rust. For home orchardists managing apple and pear trees where both insect pressure and fungal disease are consistent seasonal concerns, that combined coverage reduces the number of separate products needed.

Natural Paraffinic Oil — No Synthetic Chemistry

Bonide® All Seasons® works through the natural physical action of paraffinic (mineral) oil — smothering and suffocating pests on contact without synthetic pesticide chemistry. That natural mode of action makes it compatible with organic and low-spray growing programs and reduces the risk of pest resistance development over time.
