The amount spent by Nebraska to enforce its marijuana laws also increased by 11 percent (to an estimated $10.2 million). Most of the increase in arrests and enforcement spent came in western Nebraska (the "Nebraska Panhandle") next to the Colorado border, and particularly along Interstate 80 which traverses the entire state. Experts expressed ...
Crop scouting is the process of precisely assessing pest pressure (typically insects) and crop performance to evaluate economic risk from pest infestations and disease, as well as to determine the potential effectiveness of pest and disease control interventions. [1]
Mechanisms that have been scientifically verified include using strongly aromatic plants to deter pests; using companions to hide crops from pests; providing plants as nurseries for beneficial insects including predators and parasitoids; trap cropping; [6] and allelopathy, where a plant inhibits the growth of other species.

Mechanical control including tillage and flooding were also used to control weeds. In the late 19th and early 20th centuries, inorganic chemicals such as sulfuric acid, arsenic, copper salts, kerosene and sodium chlorate were used to control weeds, but these chemicals were either toxic, flammable or corrosive and were expensive and ineffective ...
Mechanical methods of weed control involve physically cutting, uprooting, or otherwise destroying weeds. On small farms, hand weeding is the dominant means of weed control, but as larger farms dominate agriculture, this method becomes less feasible. [6] On many operations, however, some hand-weeding may be an unavoidable component of weed ...
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
Mechanical weed control is a physical activity that inhibits unwanted plant growth. [1] Mechanical, or manual, weed control techniques manage weed populations through physical methods that remove, injure, kill, or make the growing conditions unfavorable. Some of these methods cause direct damage to the weeds through complete removal or causing ...
Feral cannabis is an exceptionally hardy weed, widely dispersing its seeds which can lie dormant for 7–10 years before sprouting again. [4] In Minnesota, hemp is classified among the 11 "noxious prohibited weeds" along with several species of thistle, and noted for damaging farmers' plowing equipment.
