The topic of global climate change has emerged over the past decade as the most widely discussed environmental subject in the world. It also shows no sign of taking a lower profile in coming years. The purpose of this fact sheet is to acquaint the reader with the basics of this topic by describing how global climate has changed in the past as well as why—along with a discussion of current temperature trends and what the future is likely to hold.
Problem: Waterhemp is becoming resistant to everything
Waterhemp is a dioecious species, with separate male and female plants. Cross pollination results in tremendous variability within populations, which is evident from differences in plant color and other characteristics.
This genetic variability results in a relatively high frequency of mechanisms that can impart resistance to herbicides, enabling waterhemp to develop resistance more rapidly than most weeds.
Waterhemp can produce over 1,000,000 seeds per plant.
