Announcement
Both Eclipse XC and Lontrel XC have recently been registered for glyphosate tolerant silage, grazing and grain corn. Both products have been proven assets to Western Canadian farmers for many years in canola and are now a tool for corn growers. Offering trusted control on hard to kill weeds such as advanced wild buckwheat, Canada thistle and even volunteer alfalfa. With a very wide window of application, they can be applied from VE to V6.

Frequently Asked Questions
SORTAN IS
1. When can Sortan IS be applied?
Sortan IS can be used as both a pre-emergent herbicide or a early post emergent up to the V3 stage of corn. It is important to keep your corn crop weed free during this period.
2. Do I need a surfactant with Sortan IS?
If sprayed alone, Sortan IS should be tank mixed with a non-ionic surfactant such as Ag Surf or Agral 90 at 0.2% v/v or 0.2L per 100L spray solution. However, optimum control of weeds occurs when Sortan IS tank mixed with 1 full REL of glyphosate. When tank mixed with glyphosate no additional surfactant is required.
3. How long is the extended control?
7-14 days depending on environmental conditions such as soil temperature and moisture. Wild buckwheat, volunteer canola and redroot pigweed benefit from extended control better than other weeds.
4. How important is moisture for Sortan IS?
In order for Sortan IS to be effective it requires rainfall within 3 to 5 days after application. Activation occurs when the top 5 to 10cm of soil is thoroughly moistened following rainfall and the herbicide is readily available to germinating weeks. If moist conditions are not immanent, consider the timing or usage of Sortan IS.
5. How does Sortan IS preform on kochia?
Sortan IS is not registered to control kochia.
6. What can I tank mix Sortan IS with other the glyphosate?
Sortan IS is only registered with glyphosate. All forms of glyphosate (including diammonium, isopropylamine or potassium salt formulations) are approved for use with Sortan IS. It is not, however, recommended to mix different glyphosate formulations in the same tank.
7. Are there any recropping restrictions with Sortan IS?
Barley, soybeans, white beans, red clover, sorghum, sweet corn, field corn, oats, canola, spring and durum wheat, dry bean, chickpea, sunflower, field pea, lentils, flax, fababeans and potatoes can be planted 10 months after application. Winter wheat may be planted 4 months after application.
8. What rate of Sortan IS should I spray with?
For optimal residual control as a pre-seed – use at the 40ac per jug rate (30g/ac)
When spraying in crop between VE and V3 either the 40ac or 80ac (30g/ac or 15g/ac) per jug rate can be used. Please check the label and weed spectrum. And always tank mix with glyphosate.
ECLIPSE XC
1. How much more glyphosate can I / should I add?
Up to the maximum label rate on glyphosate resistant corn. Eclipse XC contains a DMA glyphosate formulation. DO NOT mix glyphosate formulations.
2. What stage can I spray Ecplise XC on corn?
Eclipse XC can be sprayed from spike to V6 stage on corn.
3. Is it safe on all corn including sweet corn
Eclipse XC is only registered on glyphosate tolerant corn hybrids and CAN NOT be sprayed on sweet corn.
4. Can I spray it preseed/pre emergent?
Eclipse XC is not registered as a pre-seed and will not be supported as pre-seed.
5. If I add more glyphosate to Eclipse XC does it matter what glyphosate I add?
We recommended topping up with a DMA formulation, such as VP480, to avoid tank mix issues like
6. What rate can I apply Eclipse XC on corn?
Eclipse XC is registered for a rate of 40 acres per case
7. What are the cropping restrictions for Eclipse XC?
