Din cate stiu eu si trifoiul are acelasi efect, deci ar putea semana trifoi alb pitic, acela nici nu trebuie tuns ca nu creste mai mult de 20 cm. Da, toate astea sunt plante fixatoare de azot si se folosesc pentru redarea fertilitatii terenurilor.

se poate folosi ierbicid total si se lasa 2 saptamani sa actioneze .apoi daca apare din nou la fel se procedeaza .

Din pacate asta e cea mai otravitoare, distructiva, cancerigena si cea mai incostienta metoda.

Popgeo, Danero, lamuriti-ma si pe mine cu toxicitatea erbicidului total, glifosat in speta, producatorul sustine ca nu are remanenta in sol, exista ceva studii serioase care demonstreaza contrariul?

Health hazards of roundup & glyphosate Section at a glance Roundup, the herbicide that most GM crops are engineered to tolerate, based on the chemical glyphosate, is marketed as a “safe” herbicide, based on outdated and largely unpublished studies by manufacturers.
But laboratory and epidemiological studies confirm that Roundup poses serious health hazards, including endocrine (hormone) disruption, DNA damage, cancer, birth defects, and neurological disorders. Some of these effects are found at low, realistic doses that could be found as residues in food and feed crops and in contaminated water.
People who eat foods made from GM crops could be ingesting potentially dangerous levels of Roundup residues. Roundup and glyphosate have been detected in air, rain, groundwater, in people’s urine, and even circulating in women’s blood. Glyphosate can cross the placental barrier and the unborn foetus could thus be exposed. The “safe” dose for Roundup exposure set by regulators is not based on up-to-date objective evidence; thus current regulations do not protect the public. Introduction Over 75% of all GM crops are engineered to tolerate herbicides. Roundup Ready (RR) soy is the most widely grown GM crop, making up 52% of all GM crops.1 RR soy is engineered to tolerate Roundup herbicide, the main ingredient of which is glyphosate. The RR gene enables farmers to spray the field liberally with herbicide.
All plant life is killed except the crop. The widespread adoption of GM RR soy in North and South America has led to massive increases in the use of Roundup and other glyphosate herbicides.2 In South America, a public health crisis has emerged around the spraying of Roundup on GM soy, which is often carried out from the air. The problem made headlines on the publication of a 2010 study by Argentine researchers showing that glyphosate and Roundup caused malformations (birth defects) in frog and chicken embryos at doses far lower than those used in agricultural spraying.

The malformations seen in the experimental embryos were similar to human birth defects reported in GM soy-growing areas of South America.

The researchers said the results were relevant to humans because humans have the same developmental mechanisms as frogs and chickens.

The study identified the pathway through which glyphosate and Roundup affect embryonic development, the retinoic acid signalling pathway.3 A report by physicians in Argentina based on clinical data reported the following health effects in people exposed to spraying of agrochemicals (mostly glyphosate) on GM Roundup Ready soy: increased incidence of birth defects, miscarriages, infertility, cancers, DNA damage (which can lead to cancer and birth defects), neurological developmental problems in children, kidney failure, respiratory problems, and allergies.4 A report commissioned by the provincial government of Chaco, Argentina, found that the rate of birth defects increased fourfold and rates of childhood cancers tripled in only a decade in areas where rice and GM soy crops are heavily sprayed. The report noted that problems centred on “transgenic crops, which require aerial and ground spraying with agrochemicals”; glyphosate was named as a chemical of concern.5 These issues are relevant not only to people living in regions where GM RR crops are grown, but for consumers who eat products made from crops sprayed with glyphosate. GM RR crops do not break down glyphosate, but absorb it. Some is broken down (metabolised) into a substance called aminomethylphosphonic acid (AMPA). Both glyphosate and AMPA remain in the plant and are eaten by people and animals. Both are toxic. Scientific evidence suggests that Roundup and other commercial formulations are more toxic than glyphosate alone – yet it was glyphosate alone that was tested by industry prior to market authorization and approved by regulators. The herbicide formulations as they are sold and used have not been properly tested and assessed for safety. -

Pai si daca e chiar atat de toxic de ce este admis pe piata si de ce producatorul nu e legat si bagat la zdup pentru ca pretinde ca nu are remanenta in sol?

ai auzit de Monsanto..... Hitlerul celor din USA ? cred ca zice destul de cat pot face .....

azi auzeam la radio cum ca Monsanto da cadou porumb pentru cai sau ceva de genu..... omu ia , nu se gandeste ca asa ii creste puterea eliminand celelalte surse si apoi devin unic pe tara si o sa impuna reguli ca si in USA unde nu mai cultivi ce iti tuna prin cap ci doar ce vor ei ....direct sau ....indirect

odati intrati intr-o tara ajung sa o corupa la nivel inalt incat sa si faca jocul asa ca nimeni nu mai comenteaza daca e rau sau bun ca si cu vaccinele de la Cantacuzino

http://www.occupy.com/article/monsantos ... rise-power

aici ai un articol cu ascensiunea lor si sa vezi ca in USA detin peste 40% din cultura de porumb prin semintele pe care le dau...

By 1998, just two years after the introduction of Roundup Ready soybeans, scientists documented the first Roundup-resistant weed. A second was found in 2000, and three more popped up in 2004. To date, there are 24 different weeds that have evolved resistance to Roundup worldwide. And once they invade a farmer’s field, it doesn’t matter if his crops are Roundup-resistant, because Roundup won’t work anymore. Either the weeds get to stay, or the farmer needs to find a new chemical, pull the weeds by hand, or find some other way to deal with the problem.

Pt ca lacomia e in caracterul oricarui politician si pt ca banul e imparatul mintzilor ticalosite. Si pt ca stiintza e cam schioapa....si mai ales pt ca oamenii sint creduli si profitul companiei e urias.

Nu numai asta, practic substantza asta produce o otravire lenta dar profunda pe termen lung din cauza ca schimba structura si proportia bacteriilor, microbilor si organismelor care mentin echilibrul si sanatatea solului..... adica distruge pe termen lung.

Ca principiu, un strop de otrava intr-un butoi de apa pura, poate sa faca intreg butoiul de apa complet otravitor, functie de tipul otravii si intensitatea ei. Unele tipuri de otrava (sa zicem de exemplu cianura) vor sta in butoi ul cu apa un timp foarte indelungat.

Pe linga aceasta, substantza respectiva si derivatzii ei se infiltreaza in pinza freatica si ajunge sa fie prezenta intr-o distributie extinsa foarte repede. La nivel celular insa treaba sta mult mai prost. Mecanismele de curatzare si aparare ale celulei sint afectate.

E cam ca si treaba cu mancarea de genul Fast-Food... aparent nu iti face rau, dar in realitate e una din otravurile perfide si lente care strica sistematic sistemul endocrin si o seama de echilibre delicate din mecanismele de autoaprare si curatzare a corpului. Raul facut este aproape iremediabil.

si atunci voi cum rezolvati problema buruienilor care nu se dau batute nicicum? Sa spunem doar de pir, ca suntem pe topicul lui, daca te apuci sa-l sapi nu prea rezolvi mare lucru, orice bucatica de radacina care a ramas in pamant inseamna o noua planta si nu ai cum sa scoti absolut tot :( Eu mai am si ceva cucuta, e imposibil sa o scoti cu radacina intreaga, are radacini adanci pana-n fundul pamantului. Si mai am palamida, si aia e teroare :roll:

Inca nu am gasit o soultie completa, dar:


O parte din ele se pot rezolva cu mulcire.

Alta parte se pote rezolva cultivind terenul respectiv 1-2 ani cu o planta care elimina buruienile.

cu perseverenta o distrugi , la gradini e aplicabil usor , la hectare deocamdata ....


naturale , in afara de ziare puse si de renumita plasa de mulcire

A.Vinegar:
The acetic acid in 5% vinegar is a desiccant that sucks the life out of plant leaves. It’s most destructive to young plants with immature roots, though it just rolls off weeds with waxy leaves, like pennywort or thistle.

Make sure you cover desirables before spraying, because vinegar is an equal opportunity killer. Keep your spray on-target by removing the bottom from a 2-liter plastic soda bottle, and placing it over the weed. Spray vinegar into the mouth of the bottle, which will keep it from splattering on your vegetables.

B. Vodka:
Don’t know if vodka makes weeds fall down dead or drunk, but 1 ounce mixed with 2 cups of water and a couple of drops of dish soap will dry out weeds that live in the sun. Doesn’t work that well on shade-loving weeds. Protect desirables, because vodka will dry them out, too.

C. Soap:
The oil in soap can break down waxy or hairy weed surfaces, making them vulnerable to desiccants. So add a few drops of liquid dish detergent to vinegar or vodka sprays to keep the solution on leaves. The soap also makes leaves shiny, which will help you keep track of what you’ve sprayed.

D. Boiling water:
After you’ve made yourself a cup of tea, take the kettle outside and pour the boiling water on weeds, which will burn up. This is a particularly good way to whack driveway and walkway weeds, because the boiling water can run off impervious surfaces and cool before it reaches border plants.

E.Salt Them…

This is another method you need to be very careful with and is best for areas where you don’t want anything to grow again, ever. But a simple sprinkling of salt along the edges of your lawn, between cracks in the sidewalk or in garden pathways will kill weeds. Be careful though, it leaves the soil barren and can damage concrete. At the end of the snowy season you can usually get a pretty good deal on rock salt, which works great for this, but any kind of salt will do.

F.Burn Them…

This is my favorite weed killing method. You can get a propane powered weed scorcher at most garden stores (or just use a handheld blow-torch, like the kind you’d use for making crème brulee). You don’t have to actually set the weeds on fire – in fact in an area with dry grass that can be pretty dangerous – just running a hot flame over them will usually cause them to lose all their internal moisture, they will shrivel up and die in just a few days

etc
