发帖数: 33885 | 1 老千们来说说这petition的论点论据有科学道理吗？
I'm Peter Stocker of Friends of the Earth, and I started a petition to the U
.S. Department of Agriculture, which says:
As someone who cares about the health of our families, our food system, and
our environment, I was very disappointed by your recent approval of Monsanto
's dicamba-resistant cotton and soybeans.
Dicamba has been linked to a range of adverse human health impacts, such as
reproductive and developmental harm. Workers, farming communities, and
children a... 阅读全帖 |

发帖数: 837 | 2 I think you got it the other way round: The normal weed killers most likely
contain 2,4-D, which was part of Agent Orange or Herbicide Orange, and
Roundup/glyphosate has nothing to do with Agent Orange.
From the wiki:

defoliants used by the British military during the Malayan Emergency and the

发帖数: 837 | 4 The right sequence to kill broadleaf weeds is to use products with
combinations of 2,4-D, MCPP and dicamba first (Ortho WBG plain, Ortho WBG
Max and many others). If those can't kill your weeds and the weeds are
listed on Ortho WBG CCO, then use WBG CCO.
Some combinations of 2,4-D, MCPP and dicamba can kill some types of
chickweed, clover, and oxalis. But with so many combinations (both active
ingredients and concentration), it is hard to tell which ones are most
effective to which, so you hav... 阅读全帖 |

SAD, Standard American Diet of high chemically refined carbs, deadlyvsida,

exercise like walking, our caloric intake covered in proven cancer causing
Dicamba and Round Up and then over drugged.
Combine this with no D-3, and there is little mystery as to why America,

发帖数: 837 | 6 Indeed, pulling is the best if you can manage it and are willing to commit
the time.
Other than that, there are chemical solutions that kill weeds but not
grasses. For example, 2,4-D can be used for dandelions and plantains;
adding Dicamba and MCPP kills a wider range of broadleaf weeds; and
Triclopyr can be used for a few tougher ones. (Note what I mentioned here
are active ingredients, not brand/product names.) For these types of
chemicals, just spray the area where you want to control weed... 阅读全帖 |

Combination herbicides that include triclopyr and dicamba are especially
effective for postemergence control.

(Reuters) - Monsanto Co (MON.N) shares were up 1.8 percent on Tuesday on
rumors Germany's BASF (BASFn.DE), the world's largest chemical maker, would
bid for the global biotech seed company.
A tie-up with Monsanto would give BASF a deeper footing in the United States
and help it compete with agricultural rivals, including DuPont's (DD.N)
Pioneer unit and Dow Chemical's (DOW.N) DowAgroSciences unit.
BASF and Monsanto declined to comment.

发帖数: 837 | 9 If you decide to use chemicals, two types will kill many broadleaf weeds
including Broadleaf Plantain:
1. Glyphosate. This is the single active ingredient in Roundup. Don't
worry about the different names/brands. Get a product with high
concentration of glyphosate. They all have similar effectiveness. Note
this one is non-selective in that it kills almost all grasses, including
good ones.
2. 2,4-D plus Dicamba and/or MCPP, for example, Ortho Weed-B-Gon regular,
not the Max or CCO version, w... 阅读全帖 |

发帖数: 837 | 10 The description is summer or winter annual or biennial.
It should be an easy to control broadleaf weed. The 2-4,D/Dicamba/MCPP
combination I mentioned above should do. The non-selective glyphosate should
also work.
As usual, read the labels carefully before application. Spot spray if you
can. |

monsanto以前有一个甜菜品种GTSB77就是同时携带CP4 EPSPS和 gox 基因。
