This could be in the form of multiple insect resistant genes, multiple herbicide tolerance genes or a combination of the herbicide and insect resistant genes. Smartstax is a brand of GM maize that has eight different genes added to it, making it resistant to two types of herbicides and toxic to six different species of insects. [33]
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 ...
Control of Verticillium can be achieved by planting disease–free plants in uncontaminated soil, planting resistant varieties, and refraining from planting susceptible crops in areas that have been used repeatedly for solanaceous crops. Soil fumigation can also be used, with chloropicrin being particularly effective in reducing disease ...
The study found that herbicide-tolerant crops have lower production costs, while for insect-resistant crops the reduced pesticide use was offset by higher seed prices, leaving overall production costs about the same. [3] [105] Yields increased 9% for herbicide tolerance and 25% for insect resistant varieties.
The practice of plant irradiation has resulted in the development of more than 2,000 new varieties of plants, most of which are now used in agricultural production. [3] One example is the resistance to verticillium wilt of the ' Todd's Mitcham ' [ 4 ] cultivar of peppermint , which was produced from a breeding and test program at Brookhaven ...
Most pathogens instead exhibit a high degree of host-specificity. Non-host plant species are often said to express non-host resistance. The term host resistance is used when a pathogen species can be pathogenic on the host species but certain strains of that plant species resist certain strains of the pathogen species. The causes of host ...
Most people are familiar with the phrase “eat your vegetables” —and it’s good advice for many reasons. Yet, fewer than 10% of people get the 2.5-3.5 cups of vegetables needed daily to ...
The best control method found for F. oxysporum is planting resistant varieties, although not all have been bred for every forma specialis. F. oxysporum f. sp. batatas can be controlled by using clean seed, cleaning up infected leaf and plant material and breeding for resistance. Fungicides can also be used, but are not as effective as the other ...
