FPWOS). Results of this experiment revealed that TS has increased the wheat grain yield significantly (20%) through conservation of soil moisture contents (16 %) and soil fertility level. TS had decreased the gullies/rills formation through the efficient removal of excess rainwater.
Fungicide pyraclostrobin has been widely employed to control plant diseases by inhibiting the mitochondrial respiration of pathogenic fungi. Due to its broad spectrum, the extensive use of pyraclorstrobin was reported to cause emerging resistance on crops. Here, we evaluated the control effect of 250 g L of pyrachlostrobin suspension concentrate (SC) against freckle disease (caused by Phyllosticta spp) on banana. Meanwhile, the dissipation and residue dynamics of pyraclostrobin in banana and soil under field conditions were determined by high performance liquid chromatography (HPLC) with DAD detection in different locations. The analytical method was validated using spiked samples at three levels, which indicated the recoveries ranged from 92.0% to 99.0% with relative standard deviations (RSDs) below 5%, providing a sensitive, precise and reliable method to monitor pyraclostrobin in banana fruit and soil. The dissipation of pyraclostrobine followed the first-order kinetics and its half-lives were 5.25 to 9.90 days. In addition, the terminal residues of pyraclostrobin in banana, banana sarcocarp and soil were below the maximum residue limit (MRL) (0.02 mg kg) after a pre-harvest interval (PHI) of 42 days, which suggesting that the use of pyraclostrobin at recommended dosages was safe to banana and the environment. In summary, we demonstrated the integrated evaluation on the disease control capacity of pyraclostrobin and its environmental behavior on banana, aiming to provide solid and basic data for the safe use of fungicide pyraclostrobin.
The Department of Livestock Services has been implementing Breed Up-gradation Through Progeny Test" Project since 2003, for selecting dairy breeding bulls based on their progeny performance. This paper describes the procedures followed for setting up field based progeny testing scheme involving private farmers and reports the data of progeny testing in Bangladesh from 2007 to 2013. Until now more than 5000 farmers, having at least one Friesian crossbred cow, were registered under this program in 22 districts of the country. Five Friesian crossbred candidate bulls were evaluated on their estimated breeding values for 100-day milk yields of 199 first calving daughters during 2007 to 2013. Out of five bulls, two bulls were found promising due to their positive breeding values compared to the others. By 2015, 100 day lactation milk yield data from more than 450 daughters of 6 candidate bulls (used in 2009) of the second batch are expected to be available for evaluation, and about 2452 daughters (heifers) of different ages produced out of 29 candidate bulls are available under field recording in different geographical areas of the country. So, proven dairy bull production through field-based progeny testing program in Bangladesh is underway.Bang. J. Anim. Sci. 2015. 44(2): 106-112
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
