According to Ian Heap, a weed specialist, who completed his PhD on resistance to multiple herbicides in annual ryegrass (Lolium rigidum) in 1988 [189] – the first case of an herbicide-resistant weed in Australia [190] – by 2014 Lolium rigidum was the "world’s worst herbicide-resistant weed" with instances in "12 countries, 11 sites of ...
The term organic herbicide has come to mean herbicides intended for organic farming. Few natural herbicides rival the effectiveness of synthetics. [ 82 ] Some plants also produce their own herbicides, such as the genus Juglans ( walnuts ), or the tree of heaven ; such actions of natural herbicides, and other related chemical interactions, is ...
Annual ryegrass (L. rigidum) is one of the most serious and costly weeds of cropping systems in southern Australia, and herbicide resistance is a frequent problem. [12] Ryegrass pollen is also one of the major causes of hay fever.
Glyphosate is believed to be the most effective herbicide for clearing vegetation before planting crops, and it is also used in domestic gardens, car parks, pavements, vineyards and orchards.
Common names by which it is known include annual ryegrass, a name also given to Italian ryegrass (Lolium multiflorum), rigid ryegrass, stiff darnel, Swiss ryegrass and Wimmera ryegrass. [1] It is a native of southern Europe, northern Africa, the Middle East and the Indian subcontinent and is grown as a forage crop, particularly in Australia ...
Lolium multiflorum (Italian rye-grass, [2] annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. [3] It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. [4] [5] It is also grown as an ornamental grass.
Ryegrass populations were large, and had substantial genetic diversity, because farmers had planted many varieties. Ryegrass is cross-pollinated by wind, so genes shuffle frequently. Farmers sprayed inexpensive Hoegrass year after year, creating selection pressure, but were diluting the herbicide in order to save money, increasing plants survival.
Roundup was the first glyphosate-based herbicide, developed by Monsanto in the 1970s. It is used most heavily on corn, soy, and cotton crops that have been genetically modified to be resistant to the herbicide. Some products include two active ingredients, such as Enlist Duo which includes 2,4-D as well as glyphosate. As of 2010, more than 750 ...
