Production of New Biopesticides from <i>Cymbopogon citratus</i> for the Control of Coffee Rust (<i>Hemileia vastatrix</i>) under Laboratory and Field Conditions.

Laboratory and Field Statistical Analysis Upon verifying the ANOVA results ( Table 1 ), it was observed that under field conditions, the factors evaluated (biopesticide, concentration and evaluation) showed highly significant triple interactions ( p < 0.01), which indicates that there is a variable effect when combining the five biopesticides at the four concentrations evaluated during a period of four weeks under field conditions.
