Abstract

Effect of Sinergism and Antagonism Mix of Herbicide Metolachlor and Pendimethalin in Soybean (Glycine max L. Merril) AreaABSTRACT. The mixture two or more herbicide are represent to anticipate weakness in use herbicide at one particular crop specially in soybean. Research was aimed to find out influence of mixture two herbicide, with under various dosage to weeds and yield of soybean. Field research was conducted from February 2006 until May 2006 at station research Agriculture faculty Padjajaran University. The factorial experiment was carried out in randomized completely block design. The two factors are Metolachlor and Pendimethalin. Our result the mixture metolachlor and pendimethalin showed synergistic and antagonistic effect to population and weeds dried matter by used Colby’s method, however with used regression method, the population of weeds showed effect synergistic, and weeds dried matter not showed effect synergistic. The mixture metolachlor and pendimethalin can increased dried yield with compared to applied single doses.

Abstract

Effectiveness Mix of Metolachlor and Pendimethalin on Weed on Soybean (Glycine max L. Merril) AreaABSTRACT. Weed management is an integral part of soybean production. In order to select the most appropriate herbicide or devise the optimum weed control system, one must be able or properly identify the weed present within a field. Research was aimed to find out influence of mixture two herbicide, with under herbicide dosage to weed and yield of soybean. Field experiment was conducted on Inceptisol from February 2006 until May 2006 at station research Agriculture Faculty Padjajaran University, 700 m above sea level. The factorial experiment was carried out in randomized complete block design with two replications. The first factors-metolachlor (doses of herbicide a.i. 0,0; 0,75; 1,50; and 2,25 kg ha-1). Application showed that herbicide metolachlor and pendimethalin had single or mixture on the studied gave higher percentage of weeds covered, and weed dry matter were lower comparison. The mixture metolachlor and pendimethalin can increased dry of yield compared to herbicide single application.
