Mites are a serious problem in Western Australian pastures.
If mites are active in the first two weeks after sowing, seedling establishment may be severely reduced. When you are sowing newly cleared land or sowing a new species of legume, the legume seed should be inoculated with the correct type of rhizobia, as effective types of rhizobia are unlikely to be present in the soil. However, rhizobia are rapidly killed when they are exposed to Le-Mat. If you mix Le-Mat with legume inoculant, nodulation may fail because most of the rhizobia on the seed have been killed. Apply the Le-Mat as a solution in water, adjusting the volumes for the different legumes as recommended by the manufacturer.
