| | Journal: Citation: V : 81 ( 6 ) P : 463-73 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub2100760 Accession (PMID): 2100760 | Matching Sentences:
[ Sen. 2, subscore: 3.00 ]: The findings of the study were as follows : exposure of uncovered hands and of the skin of the back to the concentrate was visually observed during the filling , and respectively loading operations ; During spraying exposure from airborne diluted formulation occurred ; in addition contamination of the lower parts of the body took place because of direct contact with the sprayed crop ; Determination of the amount of the urinary metabolite dimethylphosphate excreted in 24 hours urine samples demonstrated absorption of monocrotophos into the body of the spraymen .
[ Sen. 1, subscore: 2.00 ]: To support the continued use and the registration of monocrotophos , a field study was conducted at Calauan , Laguna , The Philippines , to assess exposure and the resulting health risk to 21 spraymen applying monocrotophos to rice crop by knapsack spraying during 3 consecutive days .
[ Sen. 4, subscore: 1.00 ]: However , 8 of 21 spraymen had plasma cholinesterase levels below 50% of baseline values ; --No acute adverse health effects associated with the application of monocrotophos were observed , which was in accordance with the absence of clinically significant cholinesterase depressions .
[ Sen. 5, subscore: 1.00 ]: The conclusion of the study was that the use of monocrotophos under prevailing typical conditions in the Philippines , which varies from a frequency of one application per season to a maximum of 3 applications each on 3 consecutive days per week , and where label safety instructions are not necessarily observed , is not expected to pose an acute health risk under the prevailing conditions and practices , which includes filling , spraying and cleaning activities .
[ Sen. 6, subscore: 1.00 ]: From the experience in this study it is clear that proper spraying technique and adequate use of personal protection will significantly reduce exposure .
[ Sen. 7, subscore: 1.00 ]: As such a reduction is highly recommendable , advice on proper spray procedures and adequate personal protection has been reinforced .

| Title: Indoor residual spraying with alphacypermethrin controls malaria in Pakistan : a community-randomized trial | | Author: Rowland M Mahmood P Iqbal J Carneiro I Chavasse D | | Journal: Trop . Med . Int . Health Citation: V : 5 ( 7 ) P : 472-81 Year: 2000 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10964269 Accession (PMID): 10964269 | Matching Sentences:
[ Sen. 1, subscore: 1.00 ]: We conducted a community-randomized controlled trial in Pakistan to determine the efficacy of indoor residual spraying with alphacypermethrin ( Fendona , Cyanamid , NJ , USA ) , applied at 25 mg/m2 , to prevent falciparum and vivax malaria .
[ Sen. 6, subscore: 1.00 ]: Mosquito populations were monitored by space spraying of rooms and by cattle-landing catches .
[ Sen. 7, subscore: 1.00 ]: The spray campaign took place in June 1997 and covered 96% of compounds .
[ Sen. 8, subscore: 1.00 ]: During the 7 months after spraying , the incidence of falciparum malaria was 95% lower and that of vivax malaria 80% lower in WP-sprayed than unsprayed sectors .
[ Sen. 9, subscore: 1.00 ]: Similar results were obtained for sectors sprayed with the SC formulation .
[ Sen. 11, subscore: 1.00 ]: Anopheles culicifacies was 80% less abundant and Astephensi , the predominant anopheline , was up to 68% less abundant in sprayed areas over the 7-month period .
[ Sen. 13, subscore: 1.00 ]: Sprayed surfaces lacked odour , which contributed to the popularity of the campaign .

| Title: Effects of Bacillus thuringiensis on non-target herbivore and natural enemy assemblages in tropical irrigated rice .
| | Author: Schoenly KG Cohen MB Barrion AT Zhang W Gaolach B Viajante VD .
| | Journal: Citation: V : 2 ( 3 ) P : 181-206 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub15612416 Accession (PMID): 15612416 | Matching Sentences:
[ Sen. 6, subscore: 2.00 ]: For whole communities of terrestrial predators and parasitoids , Bt sprays altered parasitoid richness in 3 of 3 sites and predator richness in 1 of 3 sites , as measured by rarefaction ( in half of these cases , richness was greater in Bt plots ) , while Spearman tests on ranked abundances showed that correlations , although significantly positive between all treatment pairs , were stronger for predators than for parasitoids , suggesting that parasitoid complexes may have been more sensitive than predators to the effects of Bt sprays .
[ Sen. 7, subscore: 2.00 ]: Species accumulation curves and time-series analyses of population trends revealed no evidence that Bt sprays altered the overall buildup of predator or parasitoid communities or population trajectories of non-target herbivores ( planthoppers and leafhoppers ) nor was evidence found for bottom-up effects in total abundances of non-target species identified in the food web from the addition of spores in the Bt spray formulation .
[ Sen. 3, subscore: 1.00 ]: Here we report results of a field study evaluating the effects of Bt sprays on non-target terrestrial herbivore and natural enemy assemblages from three rice ( Oryza sativa L ) fields on Luzon Island , Philippines .
[ Sen. 4, subscore: 1.00 ]: Because of restrictions on field-testing of transgenic rice , Bt sprays were used to remove foliage-feeding lepidopteran larvae that would be targeted by Bt rice .
[ Sen. 5, subscore: 1.00 ]: Data from a 546-taxa Philippines-wide food web , matched abundance plots , species accumulation curves , time-series analysis , and ecostatistical tests for species richness and ranked abundance were used to compare different subsets of non-target herbivores , predators , and parasitoids in Bt sprayed and water-sprayed ( control ) plots .

[ Sen. 5, subscore: 2.00 ]: The spatial niche breath , percentage of diseased leaves and sheathes , index of disease , and control effect all suggested that spraying fungicide two times in rice growth period was better than spraying it one time .
