INTRODUCTION BARNYARDGRASS
Barnyardgrass (Echinochloa crus-galli var. crus-galli) is a monocot weed in the Poaceae family.  In Brazil this weed first evolved multiple resistance (to 3 herbicide sites of action) in 2015 and infests Rice.  Multiple resistance has evolved to herbicides in the Groups A/1, B/2, and L/26.  These particular biotypes are known to have resistance to cyhalofop-butyl, penoxsulam, and quinclorac (MOA in monocots) and they may be cross-resistant to other herbicides in the Groups A/1, B/2, and L/26.

The 'Group' letters/numbers that you see throughout this web site refer to the classification of herbicides by their site of action. To see a full list of herbicides and HRAC herbicide classifications click here.

ABSTRACT - The objective of this research was to confirm the resistance of a barnyardgrass biotype (Echinochloa crus-galli) to herbicides quinclorac (synthetic auxin), penoxsulam (ALS inhibitor) and cyhalofop-butyl (ACCase inhibitor). Two experiments were carried out in a greenhouse located in Itajaí, State of Santa Catarina, Brazil. One experiment evaluating the biotype ECH 18 (known as susceptible) and one with the ECH 141 biotype (suspected to be multiple resistant). The experimental design used was completely randomized, in a 4 x 7 factorial arrangement with four replications. The first factor was the herbicide: cyhalofopbutyl (Clincher®), penoxsulam (Ricer®), quinclorac (Facet®) and propanil (Grassaid®) and the second factor consisting of seven rates of each herbicide (0.00; 0.25; 0.50; 1; 2; 4 and 8 times the label rate). The evaluations of percentage of control, plant density per pot and dry mass of shoots were performed 35 days after treatments. The rates to control 50% and 80% and the dose to provide 50% and 80% of the weed biomass accumulation and the resistance factor were estimated based on data analysis. The initial hypothesis was confirmed; the biotype ECH 141 presented multiple resistance (synthetic auxin, ALS and ACCase inhibitor). However, the herbicide propanil controlled biotype ECH 141 adequate.
