Abstract
Description
[Technical Field]
[0001] The present disclosure relates to methods of controlling weeds. More particularly, the present disclosure relates to methods of controlling weeds by applying an effective amount of a herbicide combination / composition comprising a carbamate herbicide. [Background technology]
[0002] Herbicides are pesticides used to control the growth of undesirable plants / weeds that may be harmful to crop growth, health, and yield. Traditionally, herbicides have been selected for their weed control properties and their effects on crops. Herbicides that control a wide range of weed species often have limited usefulness because they also damage crops. Furthermore, the most desirable herbicides for weed control and crop safety often have other less desirable properties (e.g., environmental and economic concerns). Therefore, desirable herbicides should also control a wide range of weeds without harming desired plants, and dissipate quickly from the soil after weed control is achieved.
[0003] Undesirable plants / weeds can be controlled using herbicides that are either selective or non-selective in nature. Non-selective herbicides damage all plants to which they are applied, i.e., both desired and undesired vegetation. In contrast, selective herbicides eliminate or inhibit the growth of undesired vegetation while leaving desired vegetation relatively unharmed. Selective herbicides are designed to control specific broadleaf or grass weeds without harming desired plants. These herbicides have low to moderate toxicity and do not cause damage to crops. Various selective herbicides are known in the art for selectively controlling grass and broadleaf weeds growing in various crops. Most of these herbicides are synthetic compounds, and some herbicides have recently raised concerns regarding their safety to humans and the environment in general.
[0004] One of the known drawbacks of selective herbicides is their slow rate of action. Often, herbicidal activity is not observed for several months after application. Moreover, herbicides often do not provide adequate weed control with a single application, resulting in the need for further applications of the same or another herbicide to achieve acceptable weed control. Furthermore, these selective herbicides pose serious toxicological and environmental concerns. Therefore, there is a need to use selective herbicides that are effective in providing weed control and are environmentally safe. Therefore, there is currently a need for safer alternatives to currently used selective herbicides. There is also a need for environmentally safe herbicides that can selectively control undesirable plants, preferably grass weeds and broadleaf weeds, while leaving other plants and crops relatively unharmed.
[0005] Purpose of this disclosure The primary objective of the present disclosure is to provide methods for efficient weed control, suppression and eradication.
[0006] Another object of the present disclosure is to provide a method for selective weed control by applying an effective amount of a herbicide combination / composition comprising a carbamate herbicide.
[0007] Another object of the present invention is to provide a method for burndown control of weeds by applying an effective amount of a herbicide combination / composition comprising a carbamate herbicide.
[0008] Another object of the present invention is to provide a method for controlling, suppressing or preventing a wide range of weeds and target plants (both dicotyledonous and monocotyledonous, broadleaf, and grass weeds) by applying an effective amount of a herbicide combination / composition comprising a carbamate herbicide.
[0009] Another object of the present invention is to provide a method of controlling weeds by applying an effective amount of a herbicide combination / composition comprising a carbamate herbicide that is safe to use, effective, and can be applied pre-emergence, post-emergence, or at the time of planting.
