The effectiveness of using herbicides can be improved by using mixed herbicides. The purpose of this study was to study the effectiveness the mixture of a IPA glyphosate + methulfuron methyl with two ratios of 24:1 and 36:1 against Ageratum conyzoides weeds. The study was conducted in Experimental Field Faculty of Agriculture, Tanjungpura University in January - March 2019. The research was arranged in accordance with the Randomized Group Design. Data analysis using probit analysis continued with combination index calculation. The results showed that the combination index of 24: 1 and 36: 1 were 0.84 and 1, respectively, the both ratio of mixed herbicide were not antagonistic to Ageratum conyzoides.Keywords: Ageratum conyzoides, glyphosate, methulfuron methyl, mixed properties

Phytophthora capsici is the causal agent of foot rot, the most destructive disease of pepper in Indonesia and difficult to control. DAS-ELISA test to protect Phytophthora antigens based on antibodies that are very useful for protected plants can only be used up to the genus. This study was aimed to determine the sensitivity of Double Antibody Sandwich Enzyme Linked Immunosorbent Assay (DAS-ELISA) to detect stem rot disease (Phytophthora capsici) in each part of pepper plants (leaves, stems, and pure isolats) with different serial dilutions.The study was done at Laboratorium Balai Karantina Pertanian Kelas I Pontianak. The sensitivity limit for each sample part of the pepper plant was tested through the dilution stage of the plant extract. The results of the sensitivity limits for each sample are different. Samples of the leaves and stems of pepper plants showed positive results of Phytopththora capsici at dilution rates of 100 and 10-1. Whereas in pure isolats positive results of P. capsici were detected until the dilution rate of 10-3. Keywords : Phytophthora capsici, ELISA, dilution

The use of a single herbicide often cannot control all types of weeds. Increase the effects of weed control. This study aims to study the effectiveness of glyphosate and methyl metsulfuron herbicides to control the Ischaemum timorense weed and determine the nature of the mixture. This research was conducted from January to April 2019, for ± 4 months in the greenhouse and Pesticide Laboratory of the Faculty of Agriculture, Tanjungpura University, Pontianak. The research was arranged in random groups. The treatment consisted of 4 types of herbicides with five dose levels and 1 control, namely glyphosate (0, 0.188, 0.375, 0.750, 1.5, 3.0) l / ha, methyl metsulfuron (0, 10, 20, 40, 80, 160) g / ha, herbicide mixture A 240/10 SL (0, 0.25, 0.50, 1.00 2.00, 4.00) l / ha and mixed herbicide B 360/10 SL (0, 0 , 25, 0.50, 1.00, 2.00, 4.00) l / ha. The target weed is Ischaemum timorense, a grass weed which is planted in a 14 cm diameter pot and a target of 3 MST (Three weeks after planting a herbicide test is applied). The variables observed are the level of weed damage that was assessed through phytotoxicity scoring and weed dry weights and analysis of herbicide mixture properties. The results showed that the higher the dose of the herbicide that was given, the more effective the suppressor was in controlling weeds. Herbicides that have been able to restore weed growth include glyphosate (G3) at a dose of 0.750 l / ha, Methyl metsulfuron (M5) at a dose of 160 g / ha, A mixture of 240/10 SL (CG3) at a dose of 1.0 l / ha , Mixture B 360/10 SL (CB3) at a dose of 1.0 l / ha. A mixed herbicide A 240/10 SL with an LD50 value of 93.2 and a mixture of B 360/10 SL is 186.92 smaller than the LD50 value of a single glyphosate herbicide 186.83 and methyl metsulfuron 27.98. The index value of combination herbicide mixture A 240/10 SL is 1.0384 and herbicide mixture B 360/10 SL is 1.0262, thus the nature of the herbicide is not antagonistic.Keywords: Glyphosate, Methyl metsulfuron, LD50, Herbicide mixture.

The use of a single herbicide is often unsatisfactory in the field. Mixing herbicides is expected to provide better control results. The purpose of this study was determine the nature of the activity formulation mixture of IPA glyphosate + methsulfuron methyl with two ratios of 24:1 and 36:1 against Cyperus rotundus weeds. The study was conducted in Experimental Field, Faculty of agriculture, Tanjungpura University, Pontianak, from January to March 2019. The research was arranged according to a Randomized Block Design. Data analysis using probit analysis continued with combination indeks calculation. The results showed that the combination index of IPA glyphosate + methulfuron methyl 24:1and 36:1 was 0,88 and 0,77 so that the two mixed herbicides were not antagonistic to C. rotundus.
