The translocation of chemical insecticides in corn plants could enhance the control Spodoptera frugiperda, based on their application form. Chlorantraniliprole and cyantraniliprole were applied via seed treatment foliar spray (VE V3) to characterize systemic action both molecules leaves that appeared after application. Bioassays with S. frugiperda quantification LC-MS/MS confirmed absorption upward chlorantraniliprole by xylem new leaves. Both caused mortality larvae up stage V6 (57.5±9.5%...

Although the brown stink bug, Euschistus heros (F.) is susceptible to entomopathogenic fungi, only a single formulation currently available on Brazilian market for its control. The objective of this work was isolate fungi with potential control E. heros, evaluate their virulence, and determine effective conidial concentrations. Thirty six different fungal isolates were obtained from soil samples diseased insects pure cultures each established potato-dextrose agar. Suspensions 1 × 108 conidia...

ABSTRACT The fall armyworm Spodoptera frugiperda is among the main insect-pests on maize crops, due to its damaging potential and control issues related larval habit of concealing itself within plant whorl. This study aimed evaluate effect water in whorl, combined with insecticides spray sets, damage caused by S. grain yield. experiments were carried out under field conditions, at two cropping seasons, both Bt-maize hybrids, a 2 × 5 + 1 factorial scheme, testing presence or absence inside...

Absorption and translocation of chemical insecticides in plants are complex processes influenced by different factors. This study investigated the chlorantraniliprole cyantraniliprole soybean greenhouse, using Helicoverpa armigera as a bioindicator quantification LC-MS/MS. Two experiments were conducted greenhouse laboratory. The data submitted to analysis variance (ANOVA) Tukey test (P ≤0.05). Significant acropetal basipetal movement leaves was confirmed for both anthranilic diamides....
