The role of pendimethalin in the integrated management of propanil-resistantEchinochloa colonain Central America

Abstract: : Pre-emergence activity of pendimethalin on propanil-resistant jungle rice (Echinochloa colona) was demonstrated in glasshouse trials. Both susceptible and resistant populations, collected from Costa Rica, were controlled by 1É25 kg ha~1, the usual application rate used in the Ðeld where Rottboellia cochinchinensis is also a problem. When applied post-emergence, propanil performance was improved by the addition of low doses of pendimethalin to the herbicide mixture. A propanil-resistant selection was controll… Show more

“…The imaging techniques described here can be used to predict seed germination, giving the farmer an indication of the following year’s field population and an evaluation of weed infestation in the field. Chemical weed control can be applied both pre- and post-weed emergence (Yadav et al, 2016); certain compounds, such as pendimethalin (tubulin interaction inhibition), can serve for both purposes (Riches et al, 1997; Yaduraju et al, 2000). The low benefit that is derived from pre-emergence herbicidal treatment is related largely to the uncertainty about the subsequent year’s weed infestation rates.…”

“…In all cases except the E. colona samples, whole panicles were collected from individual plants and kept separately. The E. colona samples originated from bulk collections in farmers' fields from Costa Rica and Colombia (see Table 1) and have been maintained at IACR‐Long Ashton, UK, with distinct accession numbers (Caseley et al ., 1997; Riches et al ., 1997). For all 24 samples, five seeds per panicle were germinated and grown individually.…”

“…Fisher et al (1993) suggested that one way to reduce the level of propanil resistance in Echinochloa sp is to use commercial formulation of propanil or molinate as they are more effective than propanil alone. Riches et al (1997) recommended that pendimethalin improved post-emergence control in the field compared to the standard propanil treatment and can provide residual pre-emergence control of late-germinating individuals, so reducing the propanil selection pressure. For effective E. colona control, growers apply propanil (3·84 kg ha -1 ) at 10 and 20 days after planting (DAP) followed by one application of fenoxaprop-P-ethyl (0·045 kg ha -1 ) at 35 DAP, and one application of pendimethalin at 1·5 kg ha -1 provided an effective replacement for propanil.…”
