Abstract/ Executive Summary:

An experiment was conducted in the Plant Pathology Laboratory, Bangladesh Agricultural University, Mymensingh during winter 2011-2012 to evaluate the efficacy of some fungicides for improving the quality of seeds of lentil. The test fungicides were Rovral (0.2%), Secure 600 WG (0.2%), Bavistin 70 WP (0.2%), Captan 50 WP (0.2%). BARI Masur-1 was used in the experiment. Around 57% healthy seed was recorded from the Secure 600 WG sprayed plot. Germination was 21.63% in case of Secure 600 WG against 18.94% in Control. Four fungal pathogens namely Aspergillus flavus, Aspergillus niger, Penicillium spp. and Fusarium spp. were associated with lentil seeds. Among the treatments, Secure 600 WG (0.2%) was found to be the most effective fungicide in controlling seed borne fungi. Germination (%) and seedling vigor was also increased due to application of Secure 600 WG (0.2%). The highest germination was found to be 86.00% and the highest vigor index was 522.02 in Secure treated plants in comparison to 63% and 250.11 in untreated control.

Commodity: Lentil, Fungicide

Objectives:

Objective of the study was to evaluate the efficacy of some fungicides for improving the quality of seeds of lentil.

Methodology:

The experiment was carried out at the laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh during October, 2011 to May, 2012. BARI Masur-1 a susceptible variety was chosen for the study. There were five treatments viz. T₁: Rovral 50 WP (0.2%) (Iprodione); T₂: Secure 600 WG (0.2%) (Fenamidone + Mancozeb); T₃: Bavistin 70 WP (0.2%) (Carbendazim); T₄= Captan 50 WP (0.2%) and T₅: Control in the trial. Completely Randomized Block Design (CRD) was followed and there were three replications. Seed samples were collected after harvesting from the treated plot. Seed samples were placed in a clean brown paper bag, labeled properly and preserved at 5-8ºC temperature in refrigerator for subsequent use. Dry inspection: Randomly 400 seeds were taken from each seed sample. The seeds were categorized into the groups of apparently healthy seeds, discolored seeds, spotted seeds, unfilled grains and deformed grains. Separations of different categories of seeds were done with unaided eyes. A 10x hand lens was used whenever necessary. Species wise insect population, inert matter, and other plant parts were also observed but not counted in this experiment. The different seed categories were expressed in percentage. Seed health test (blotter method): Four hundred seeds were randomly selected from each treatment. The seeds were placed on water soaked three folds blotter paper in plastic petridishes after 15 days of harvesting. In each petri dish, 25 seeds were plated at equal distance. The seeds were incubated at 22±2ºC under 12 hours cycle of alternating near ultraviolet light and darkness. After 8 days of incubation, seed borne pathogens were detected. Numbers of seeds sprouted were counted and the data were expressed as percentage. Germination and Seedling vigor test: Germination test was carried out. Iron trays (30 cm x 30 cm) were used for this test. The trays were filled in with moist sand at field capacity. Four trays were used for each treatment (fungicide). One hundred seeds were sown in each tray. Polyethylene bags were used for mulching. After 15 days of sowing, percent germination was calculated. Ten seedlings from each tray were randomly selected, and shoot and root length was measured. The seedling vigor index was determined by the following formula. Data analysis: Collected data were statistically analyzed using MSTAT-C Computer Package Program. The significance of the difference among the treatments means was estimated by the least significant difference (Lsd) test at 5% level of probability.

Achievement/Findings:

There is positive influence of seed treatment with fungicides on seed health status of Lentil seeds. Seed treatments with Secure 600 WG (0.2%) resulted in better germination and vigour, reduced the number of contaminated and dead seeds. Among the different fungicides tested Secure 600 WG (0.2%) was the most effective fungicide in controlling seed borne fungi.
