I couldn’t get to spray the aphids on the corn yesterday, but I hope to do it today…
The KillaSpray was last used to poison the leucaena, which means Roundup was used. The boys rinsed out the bottle and it does not smell (but they knocked part of my lawn around a bit…). Mr D’s advice is to take it to the patch of parthenium in the milking yard, rinse it out again and again over the parthenium, at the same time spraying clean water through the spray wand.
Will just water do? Or should I add a drop or two of the water-based Shell® detergent as well?
