What If The Field Has Both Soybean Aphids And Twospotted Spider Mites?
– Ron Hammond, Bruce Eisley One of the problems that we may encounter this year is the possibility of some fields having problems with both soybean aphid and twospotted spider mite at the same time. In these particular cases, the choice of insecticides to use becomes a little more difficult. For example: most of the pyrethroids are labeled for soybean aphid but are not labeled for the mite (as mentioned, the exception is Warrior which is labeled for twospotted spider mite for suppression only) and would not do a good job on mites.
