Horrilble weed problem for a newbie

Plants generally need to be in active growth for most herbicides to be effective. Horticultural vinegar is a 'natural' choice but has its own drawbacks. Glyphosate (RoundUp) is commonly used for this purpose and works as well but with less of a long term environmental impact. It breaks down in the soil quite rapidly and is far less of a pollutant than most commercial fertilizers are. This is what is known as "damning with faint praise". If you have any consideration for the planet, you will refrain from using chemical fertilizers as they kill microorganisms in the soil and reduce top soil, thus making the user more dependent on them, in ever increasing quantities to maintain the same level of crop production, until the system crashes from lack of topsoil. Both are broad spectrum herbicides, meaning they can damage anything they are sprayed on. Follow label directions explicitly and avoid using if any kind of breeze. http://www.ehponline.org/members/2005/7728/7728.html Our studies show that glyphosate acts as a disruptor of mammalian cytochrome P450 aromatase activity from concentrations 100 times lower than the recommended use in agriculture; this is noticeable on human placental cells after only 18 hr, and it can also affect aromatase gene expression. It also partially disrupts the ubiquitous reductase activity but at higher concentrations. Its effects are allowed and amplified by at least 0.02% of the adjuvants present in Roundup, known to facilitate cell penetration, and this should be carefully taken into account in pesticide evaluation. The dilution of glyphosate in Roundup formulation may multiply its endocrine effect. Roundup may be thus considered as a potential endocrine disruptor. Moreover, at higher doses still below the classical agricultural dilutions, its toxicity on placental cells could induce some reproduction problems. -- - Billy "For the first time in the history of the world, every human being is now subjected to contact with dangerous chemicals, from the moment of conception until death." - Rachel Carson http://www.youtube.com/watch?v=WI29wVQN8Go http://www.haaretz.com/hasen/spages/1072040.html |
