How it works
Intervix is absorbed through the leaves, green stems and roots of susceptible weeds and moved from the point of contact throughout the plant. Weeds will either die or will remain stunted and will not compete with the crop. Symptoms of kill may take one to two weeks to develop, with death occurring up to one month from treatment. Symptoms first appear at the growth points where young foliage becomes discoloured and distorted before dying.
Intervix is primarily a post-emergence product. Best results will be achieved when good contact and coverage of weeds occurs and weeds are actively growing.
Intervix also has some residual soil activity under good soil moisture conditions. Residual effects on weeds can be reduced when dry soil conditions follow application before the herbicide has moved to the root zone. Best results will be achieved when application is made to moist soil or if approximately 10 mm rain follows within several days of application.
Vigorous crop growth will assist in suppressing weeds not completely killed and those germinating later.
