out custom spraying today all in crop spray , butress , bit of insectiside , lyquid fert & so on , had a 30 ha block added 25g broadstrike , (granuals ) , using rain water out of a concrete tank , it went real sticky & blocked all my filters . put broadstrike last , never had problems before sprayed this mix over thousands of hectares , all i can put it down to is the cold tank water , we are in the middle of winter , has anyone had this problem before ? The landmark agro that done the reco sheet showed up just as i blocked up , he helped me dissolve the mess !!!
