Fogging, also known as ultra-low volume treatment, utilizes very fine particle sizes to greatly reduce spray volume when applying chemicals. These small particle sizes enable products to be applied uniformly and to reach areas in the crop canopy and the undersides of leaves that may otherwise be missed by hydraulic sprayers. Fogging reaches all surfaces within the greenhouse space including under benches to nooks and crannies in the floors and structures.
What might growers want to fog?
Sanitizers – Fogging sanitizers can cut down on labor associated with spraying for hard surface sanitation. Dramm Autofog and Mini AutoFog can be left unattended outside of normal work hours and allowed to fog a sanitizer throughout a workspace. Sanitizers such as ZeroTol 2.0 can be run through these foggers when using stainless steel spray nozzles.
Biological and other water-based pesticides – Using a Dramm Coldfogger, Dramm Turbo ULV, or the Dramm BioPulsFOG, products containing live active ingredients can be applied evenly and thoroughly throughout the production space. These types of products are often used to treat insects such as aphids, or foliar fungal diseases such as Botrytis, powdery mildew, or leaf spots. Additionally, Coldfoggers and thermal foggers greatly decrease the time required to spray when compared to hydraulic sprayers and AutoFog equipment.
What should growers avoid fogging?
Oils – Many oils are technically compatible with fogging, but the trouble lies in their mode of action. Oils work through suffocation, filling all the air openings of insects or mites. Fogging produces very small-sized particles, one of the strengths of fogging, which ensures a highly uniform but thin layer of pesticide without using large amounts of water. While ideal for most pesticides, this action works against the coating and suffocating action of horticultural oils. Fogging oils also covers equipment with a fine layer of oil that may be detrimental to things such as lights or other mechanical fixtures.
Sulfur – Fogging, burning, or atomizing sulfur may be an effective insecticide and fungicide, but this practice carries with it several dangers and detriments, as well as not being an EPA approved practice. Sulfur vapors represent significant human health hazards, and over time sulfur vapors erode the integrity of poly materials. Plastics become brittle and useable lifetime is significantly reduced.
