ABSTRACT
Two propanil-resistant biotypes of Leptochloa chinensis infesting rice fields of Kelantan, Malaysia (including the fields of the National Planter’s Organization in Pasir Mas and Rantau Panjang) were identified in a glasshouse study. Dose-response tests conducted using leaf discs revealed that L. chinensis from rice fields of Pasir Mas and Rantau Panjang have developed resistance to propanil. Based on visual assessment, leaf disc tests indicate that the resistant biotypes are 2-fold more resistant than their respective susceptible biotypes.
ABSTRAK
Dua biotip Leptochloa chinensis yang rintang terhadap propanil dan tumbuh di sawah padi, Kelantan, Malaysia (merangkumi sawah padi KADA di Pasir Mas dan Rantau Panjang) dikenalpasti dalam suatu kajian rumah kaca. Ujian gerak balas dos dengan menggunakan cakera daun mendedahkan L. chinensis dari Pasir Mas dan Rantau Panjang telah rintang terhadap propanil. Berdasarkan pentaksiran visual, cakera daun menunjukkan biotip rintang ialah dua kali lebih rintang berbanding biotip rentan masing-masing.
