In 1990 sulcotrione was introduced for post- emergence weed control in corn. Isoxaflutole opened the market more broadly for HPPD inhibitors when it was introduced in 1996 for corn and sugarcane, and for use as a pre-emergence herbicide that could control broadleaf weeds as did sulcotrione, but also additional grass weeds.
Hot and dry conditions reduce control. Clay content, soil pH or soil organic matter has little effect on QPE. The usual application is through a 30-150 L/Ha tank mix. [5] QPE is a post-emergent herbicide and is absorbed through the leaves, whence it is quickly translocated to the roots and growing sections of the plant.
Ethofumesate is a pre- and post-emergence [1] herbicide used on sugar beets to control weeds, notably blackgrasses. UK registration in 2016 is planned for pre-emergence use on wheat as an auxiliary component of tank mix. [2] Ethofumesate is used in Australia, to control wintergrasses in turfgrasses, along fencelines and tree plantations.
A manual backpack-type sprayer Space treatment against mosquitoes using a thermal fogger Grubbs Vocational College students spraying Irish potatoes. Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
The genes contained in these seeds are patented. Such crops allow farmers to use glyphosate as a post-emergence herbicide against most broadleaf and cereal weeds. The health impacts of the product as well as its effects on the environment have been at the center of substantial legal and scientific controversies.
Atrazine is a chlorinated herbicide of the triazine class. [2] It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn), [3] soybean [3] and sugarcane and on turf, such as golf courses and residential lawns.
One example is the "double knock" system used in Australia. [35] Before planting a crop, weeds are sprayed with glyphosate first, then followed seven to ten days later by a paraquat herbicide. Although twice as expensive as using a single glyphosate spray, the "Double Knock" system is widely relied upon by farmers as a resistance management ...
2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
