Benzobicyclon, was introduced in 2001 for control of broadleaf weeds and some sedges that are problems in rice, that had become resistant to sulfonylurea herbicides. Mesotrione was introduced in 2002 and like sulcotrione is a triketone, so it is effective on the same weeds and crops, but is more potent, making it more useful in mixes with other ...
Diflufenican has shown control over: wild radish, wild turnip, turnip weed, [6] multiply herbicide resistant waterhemp [7] (applied pre-emergence), hedge mustard, Indian hedge mustard, charlock, deadnettle, prickly lettuce, pheasant's eye, [11] Galium aparine, ivy-leaved speedwell and Veronica persica; [10] and suppression of capeweed, crassula ...
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.
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.
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [ 2 ]
It has been found nontoxic to bees and marginally toxic to fish (rainbow trout LC 50 (96 hr) = 117 ppm). [ 4 ] Garlon's fact sheet for their triclopyr ester product indicates that triclopyr is highly toxic to fish, aquatic plants, and aquatic invertebrates, and should never be used in waterways, wetlands, or other sensitive habitats.

Glyphosate-based herbicides are herbicides made of a glyphosate salt usually combined with other ingredients needed to stabilize the formula and allow penetration into plants. Roundup was the first glyphosate-based herbicide, developed by Monsanto in the 1970s.
As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [ 7 ] [ 8 ] While the use of Roundup Ready crops has increased the usage of herbicides measured in pounds applied per acre, [ 9 ] it has also changed the herbicide use profile away from atrazine , metribuzin , and alachlor [ citation needed ] which are more ...
