Plan spring sprays for best control
Technical manager Manda Sansom explains: "Following a long, cold winter the spring of 2015 has seen pleasant warm spells in April and early May but with high diurnal temperature ranges and overnight frosts. Applying glyphosate too early can lead to reduced weed control."
Ms Sansom points out that understanding how glyphosate works can prove very helpful in understanding how performance varies in different situations.
"Glyphosate works by leaf uptake and translocation to the growing points in both shoots and roots. Here it blocks the biochemical pathway producing amino acids - the building blocks for protein and causes a slow death by starvation."

The variable weather can also slow the effects of herbicide applications.
"Even with good leaf coverage, low soil temperatures and high diurnal air temperature ranges resulting in slow plant growth mean visible symptoms can take up to four weeks rather than the expected 10-14 days. However, the end result will be the same."
The latest development in Monsanto's long history of continual product development helps amenity professionals meet the challenge of catchy conditions.
Roundup ProVantage is more concentrated at 480g glyphosate per litre and the optimised blend of surfactants as well as the high loading makes it Monsanto's most advanced amenity glyphosate.

Improved reliability in hot and dry or cool and dry conditions helps make the most of weather windows and benefits contractors at a busy time of year.
Purchasers also have the benefit of Monsanto's long experience in getting the best out of glyphosate.
"Operators should pay close attention to correct water volumes and proper sprayer calibration, choosing appropriate nozzles and avoiding drift for optimum efficacy.
