What ratio to kill honey sickle and ivy?
Scott E on May 25, 2018
BEST ANSWER: Apply Hyvar® X-L Herbicide at the rates indicated in the table below. Use the
lower rates for short-term control or in areas with less than 20 inches of annual
rainfall. Use the higher rates for longer-term control or in areas with greater
than 20 inches of annual rainfall. Annuals—3/4 to 3 gallons per acre

Application rates may vary with soil texture and organic matter content. Use
the lower rates on coarse textured soils, such as loamy sand and sandy loam.
Use an intermediate rate on medium textured soils, such as loam, silt loam, silt,
clay loam, and sandy clay loam and the higher rates on fine textured soils,
such as silty clay loam, clay loam, sandy clay, silty clay, and clay. For soils low
in organic matter or carbon use the lower rates and for soils with higher levels
of organic matter or carbon use the higher rates.
Lower rates may be used in areas where it is desirable to maintain control of
weeds that have been controlled with previous applications of residual
herbicides. Use the higher rate as an initial treatment in areas where weeds
have not been controlled with previous herbicide applications or in areas where
perennial weed pests have become established.

Will hyvar x get rid of invasive bamboo ?
Shirley J on Oct 14, 2017
BEST ANSWER: I would recommend using a combination of Roundup and Miracle Grow to control Bamboo, you will want to mix the 2 spray to run off with complete coverage. Then allow the Bamboo to completely dye, do not cut it down. After a couple of weeks you will see that the plants just simply pulls out of the grown.
