Badherent malathion flour granules as an environmentally selective control for chewing insect pests of dent corn ears. Indirect reduction of mycotoxigenic ear molds.

In a 2 year comparative study the incidence of potentially mycotoxigenic Fusarium fungi was significantly reduced by a single hand application of 0.1% (AI) malathion granules at 11 kg/ha (0.011 kg/ha [AI]) compared with control plots, and was approximately equal to plots receiving 5 sprays of malathion at 1.1 kg/ha (AI) each. In a second series of studies at this site, the use of IZ malathion granules at 11 kg/ha (0.11 kg/ha [AI]) significantly reduced the incidence of chewing corn ear insect pests and visible Fusarium mould in 2 corn hybrids that differed in relative resistance to Fusarium moniliforme. Although year and hybrid effects were involved, there was generally a positive association between insectdamage and incidence of mould in the 1994 and 1995 hand application studies. Relative insect damage at harvest was significantly correlated with fumonisin levels of the hybrids treated in 1995.
