Fomesafen is the ISO common name [2] for an organic compound used as an herbicide. It acts by inhibiting the enzyme protoporphyrinogen oxidase (PPO) [3] which is necessary for chlorophyll synthesis. Soybeans naturally have a high tolerance to fomesafen, [3] [4] via metabolic disposal by glutathione S-transferase.
4-Hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors (HPPD inhibitors) are a class of herbicides that prevent growth in plants by blocking 4-Hydroxyphenylpyruvate dioxygenase, an enzyme in plants that breaks down the amino acid tyrosine into molecules that are then used by plants to create other molecules that plants need.
Lactofen is applied as a foliar spray and is commonly used to control broadleaved weeds in soybeans, cereals, potatoes and peanuts. It may be combined with oil or fertilizer adjuvants and surfactants. Some formulations include solvents such as xylenes and cumene. [1] It is also used as a fungicide for Sclerotinia white moulds on soybean. [4] [5 ...
Amaranthus tuberculatus, commonly known as roughfruit amaranth, [4] rough-fruited water-hemp, [5] tall waterhemp, or common waterhemp, [6] [7] is a species of flowering plant. It is a summer annual broadleaf with a germination period that lasts several months. [8] Tall waterhemp has been reported as a weed in 40 of 50 U.S. states. [9]
Dicamba is a selective and systemic herbicide that kills annual and perennial broadleaf weeds. [10] Its primary commercial applications are weed control for grain crops and turf areas. It is also used to control brush and bracken in pastures, as well as controlling legumes and cacti.
Pendimethalin protects crops like wheat, corn, soybeans, potatoes, cabbage, peas, carrots, and asparagus. It is used to control annual grasses and certain broadleaf weeds which interfere with growth, development, yield and quality of agricultural and horticultural crops by competing on nutrients, water and light.
One major complication to the use of herbicides for weed control is the ability of plants to evolve herbicide resistance, rendering the herbicides ineffective against target plants. Out of 31 known herbicide modes of action, weeds have evolved resistance to 21. 268 plant species are known to have evolved herbicide resistance at least once. [ 59 ]
Triclopyr is a selective weedkiller used to control dicotyledonous weeds (i.e. broadleaf plants) while leaving monocotyledonous plants (mostly bulbs, grasses and conifers) unaffected, [2] or to control rust fungus on soybean crops.
