Three experiments were carried out in order to evaluate the effect of the herbicide clomazone, alone and mixed with propanil and 2,4-D on weed control and toxicity to rice cv. Milagro Filipino, growing under upland conditions. All the experiments were established in Los Naranjos, a rice-growing area located in the Municipality of Tres Valles, in the state of Veracruz. The dominant weed species in the experimental plots were Cyperus iria, Echinochloa colona, Cyperus rotundus, Scleria setuloso-ciliata and Malachra fasciata. Clomazone applied preemergent, efficiently controlled E. colona at 0,72 and 0,96 kg a. i./ha, but its effect was partial and temporary on S. setuloso-ciliata and it had no effect on C. iria and C. rotundus. Mixture of clomazone + propanil + 2,4-D efficiently controlled E. colona and C. iria from 0.60 + 1.44 + 0.24 kg a. i./ha. It also had a good initial control of C. rotundus, but its effect was completely lost between 45 and 60 days after the application and its effect on S. setuloso-ciliata was influenced by the soil moisture: the higher the moisture the better this weed was controlled and viceversa. Rice grain yields obtained in plots where clomazone, alone or mixed with propanil and 2,4-D was applied were statistically similar to those obtained in plots where the weed control regional treatment was applied.

“…Timing, duration, and flooding depths will determine the degree of weed suppression under anaerobic conditions (Ismaila et al 2015). In Nigeria, chemical weed control has proven to be effective under irrigated field conditions in the past (Imeokparia 1990) when integrated with good land preparation and proper water management (IITA 1974). Most lowland fields where rice is cultivated in Nigeria are rainfed, situated along coastal plains, and characterized by undulating land terrains without bunds or good drainage systems.…”

Weed management in rainfed lowland rice ecology in Nigeria – challenges and opportunities

2022

Developing an effective weed management strategy is crucial to sustainable rice production in Nigeria. Rainfed lowland ecology contributes significantly to the volume of rice cultivated in the country in terms of yield and land acreage. Nevertheless, increased weed infestation remains one of its major production constraints. This review highlights the strength and weaknesses of weed management practices in rainfed lowland ecology, potential research gaps, and discusses the potential of a sustainable weed management strategy for lowland rice. In this review, a rainfed lowland situation is described (where water is limited) to engage flooding as a potential weed control option, due to the undulating land terrains. Effective weed management begins with creating a weed-free environment at the critical crop growth stages, such that broadcasted or transplanted rice seedlings can efficiently utilize water, nutrients, and light. Sustainable weed management practices in Nigerian lowland ecology would therefore imply that farmers begin to incorporate crop rotation to suppress problem weed pressure in continuous rice cropping systems, adopt conventional or minimum tillage to enhance herbicide efficacy and early establishment of rice, adopt weed competitive and high yielding cultivars, and practice appropriate spacing, seeding rate, and seeding methods that can support easy adoption of mechanical weeders and optimum plant population to suppress weed pressure at a later growth stage. This is feasible where farmers are supported with infrastructural facilities, farm machinery, and necessary inputs. Future research should engage lowland rice farmers in specific agroecological zones.

“…Sin embargo, con la aplicación en postemergencia temprana de herbicidas residuales en mezcla con propanil se tiene la ventaja de que con una sola aplicación se pueden controlar las malezas emergidas, a la vez que se evitan nuevas emergencias de malezas. De esta manera, el propanil se ha mezclado con oxadiazón (Silveira y Aquino, 1983;Esqueda y Acosta, 1985), piperophos (Imeokparia, 1990), tio-bencarbo y pendimetalina (Ríos, 1991;Stauber et al, 1991;Drees, 1996). El clomazone es un herbicida residual que se aplica en preemergencia o en presiembra incorporado y tiene un excelente control de malezas gramíneas y algunas especies de hoja ancha (Thomson, 1993).…”
