MULTIPLE RESISTANT JUNGLERICE
(Echinochloa colona)


Multiple Resistance: 2 Sites of Action
ACCase inhibitors (A/1)
EPSP synthase inhibitors (G/9)

Venezuela, Cojedes
INTRODUCTION JUNGLERICE
Junglerice (Echinochloa colona) is a monocot weed in the Poaceae family.  In Venezuela this weed first evolved multiple resistance (to 2 herbicide sites of action) in 2008 and infests Rice.  Multiple resistance has evolved to herbicides in the Groups A/1, and G/9.  These particular biotypes are known to have resistance to fluazifop-P-butyl, and glyphosate and they may be cross-resistant to other herbicides in the Groups A/1, and G/9.

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

Resistance to glyphosate and fluazifop-p-butyl herbicide of a Echinochloa colona L.  population Echinochloa colona L. is one of the most important weed in rice crop under direct sowing in Venezuela and its control mainly is based on the use of herbicides. The inefficient control of populations of this weed by glyphosate and fluazfop-p-butyl in rice fields in Cojedes state, made think the resistance occurrence, reason why it was carried out be this evaluation. The field affected by the problem was sampling and seeds of the weed were collected (resistant population); also seeds of the same weed in a field in ecological production were collected where applications of herbicide have been made never (susceptible population). The used methodology is based on the proposal by Seefeldt et al. (1995). It was used a completely randomized design with 6 treatments (herbicide dose) and 22 repetitions for each population and herbicide evaluated. Each repetition consisted of a pot with 2 to 3 plants of the weeds. The doses of herbicide evaluated were: 0; 21,88; 43,75; 87,5¸175 and 350 g.ha-1 of fluazifop-p-butil and 0; 337,5; 675; 1350; 2700 and 5400 g.ha-1 for glyphosate. Passed 21 days it was come to determine the aerial fresh weight of the plants for the calculation of the weight average by plant in each repetition. The data was analyzed by analysis of variance and fit to log-logistic model of dose-response for the calculation of the resistance index (RI). The evaluated population was resistant to both herbicides, obtaining a RI= 2.25 for fluazifop-p-butil and RI=4,18 for glyphosate.
