Depending on the area of operation and trawl used, trawlers range in size from open boats, undecked, powered by outboard engines up to large freezer trawlers and factory trawlers which can fish in the most distant waters.

Trawling is a method of fishing that involves pulling a fishing net through the water behind one or more boats. The net used for trawling is called a trawl. (https://en.wikipedia.org/wiki/Trawling)

Common smut of maize is a disease caused by a fungus (Ustilago zeae) which can be spread via wind and water. It can also survive on plant debris and in soil for long periods of time.

Tree form is the form of a perennial plant, usually having secondary thickening, with a three-dimensional crown supported off the ground by a more or less trunk-like main stem or stems, so that the crown is typically sparse or absent near ground level. There is no minimum size for tree form (see bonsai, seedling). (https://www.treeterms.co.uk/files/definitions/tree-form.html)
A woody perennial with a single main stem, or in the case of coppice with several stems, having a more or less definite crown. (Global Forest Resources Assessment 2020, FAO 2018)

Hyptis suaveolens is a coarse erect annual or often a perennial with stems that become more or less woody and persist. Usually much branched, it is sometimes as much as 2.5 metres high but is generally much lower. The plant has a range of food and medicinal uses, being often harvested from the wild for local use. Studies have found that H. suaveolens is effective as an insecticide. (http://tropical.theferns.info/viewtropical.php?id=Hyptis+suaveolens)
A whirl or circling current of air or water, different and differentiated from the general flow, and brought about by pressure irregularities as in the downwind (lee) side of an obstacle. (TRG(112)/GICM, FAO, 2005. Wildland Fire Management Terminology, FAO (Updated Jan 2005).)
