Allelopathic interference of Sapindus saponaria root and mature leaf aqueous extracts on diaspore germination and seedling growth of Lactuca sativa and Allium cepa Rev. Bras. Bot.
Grisi,Patrícia Umeda; Gualtieri,Sônia Cristina Juliano; Ranal,Marli Aparecida; Santana,Denise Garcia.
Sapindus saponaria (soapberry) is a species that presents a great diversity of chemical compounds, such as saponins; however, few studies have examined the allelopathic effect of this species. Therefore, this study provides an evaluation of the allelopathic potential of aqueous extracts of the roots and mature leaves of S. saponaria on the germination of diaspores and seedlings growth of lettuce (Lactuca sativa) and onion (Allium cepa). The aqueous extract was prepared in the proportion of 100 g of dry plant material in 1,000 mL of distilled water (a concentration of 10% w v-1), and diluted with distilled water to 7.5, 5.0 and 2.5% concentrations. The mature leaf extracts caused delay and decrease in the germination process of the lettuce and onion...

Larvicidal potencial of Sapindus saponaria (Sapindaceae) against Rhipicephalus sanguineus (Latreille, 1806) (Acari: Ixodidae) Arq. Bras. Med. Vet. Zootec.
Fernandes,F.F.; Leles,R.N.; Silva,I.G.; Freitas,E.P.S..
The larvicidal potential of the crude ethanolic extracts (CEE) of the stem peel of Sapindus saponaria was evaluated against Rhipicephalus sanguineus. Lethal concentrations (LC), were calculated by preparing CEE solutions at different concentrations in distilled water. Larvae fasted for 14-21 days were utilized in the bioassays, after incubation of engorged females collected from infested environments frequented by dogs in several neighborhoods of Goiânia, GO. Bioassays were performed in a specially constructed biological chamber for testing botanical acaricides, acclimatized to 27±1ºC, RH>80%. The larvae were counted on filter paper envelopes impregnated with the solutions or distilled water and larval mortality observed after 48h. S. saponaria showed...

Larvicidal potential of Sapindus saponaria to control the cattle tick Boophilus microplus PAB
Fernandes,Fernando de Freitas; Freitas,Edméia de Paula e Souza; Costa,Anna Carolina da; Silva,Ionizete Garcia da.
The objective of this study was to evaluate the larvicidal potential of a crude ethanol extract (CEE) of soapberry Sapindus saponaria stem peel on the cattle tick Boophilus microplus. Tick larvae obtained by incubating engorged females, collected from naturally infested cattle, were placed in envelopes of filter paper impregnated with different concentrations of CEE in the test group, and distilled water in the control group. Four repetitions were made with each solution (n>120). Mortality was observed after 48 hours. Lethal concentration values of 1,258 ppm (LC50) and 6,360 ppm (LC99) were obtained.

Phytotoxic activity of crude aqueous extracts and fractions of young leaves of Sapindus saponaria L. (Sapindaceae) Acta Botanica
Grisi,Patrícia Umeda; Gualtieri,Sônia Cristina Juliano; Ranal,Marli Aparecida; Santana,Denise Garcia de.
The aim of this study was to evaluate the phytotoxic potential of aqueous extract of young leaves of Sapindus saponaria L. (soapberry) on the diaspore germination and seedling growth Lactuca sativa L. (lettuce) and Allium cepa L. (onion), as well as to determine, by bioassay-guided fractioning, whether the fractionated extracts of those leaves are phytotoxic to Triticum aestivum L. (wheat) coleoptiles. The aqueous extract was prepared using 100 g of dried plant material dissolved in 1000 ml of distilled water, resulting in a concentration of 10.0%. Distilled water was added in order to obtain dilutions of 7.5%, 5.0%, and 2.5%. The extraction was carried out with young leaves (in powder form) and organic solvents of various polarities. We fractioned the...

Toxicity of extract of Magonia pubescens (Sapindales: Sapindaceae) St. Hil. to Control the Brown Dog tick, Rhipicephalus sanguineus (Latreille) (Acari: Ixodidae) Neotropical Entomology
Fernandes,Fernando F.; D’alessandro,Walmirton B.; Freitas,Edméia P.S..
The action of crude ethanol extract of the stem bark of the soapberry Magonia pubescens St. Hil. was studied upon larvae of the Brown Dog tick Rhipicephalus sanguineus (Latreille). Tick larvae were obtained by maintaining gravid females in an incubator, after collecting them from naturally infested kennels. The tick larvae were placed in envelopes of filter paper impregnated with different concentrations of the extract dissolved in dimethylsulfoxide (DMSO) and distilled water. Four tests were repeated with each solution (n > 120). The control was carried out in DMSO and distilled water. The bioassays were performed at 27±1°C, RH > 80% and 12:12 light cycle. Mortality was observed after 48h exposure. All motionless larvae were considered to be dead....

ประสิทธิภาพของผลมะคำดีควายในการควบคุมหอยเชอรี่ในแปลงนาข้าวทดลอง Thai Agricultural
Urassaya Boonpramuk; Thasdaw katenate; Wannaphan Janlapha; Wantana Sriratanasak.
Efficacy test of pericarps of soapberry (Sapindus emarginatus Wall) to Golden Apple Snail (Pomacea canaliculata Lamarck) was conducted in 2 x 5 meter rice field plots at Prachin Buri Rice Research Center in 2013. RCB design was used in this experiment. Five plots were treated with suspension of pericarps of soapberry at rates 2, 3, 4, 5 and 6 kg/rai and compared with other two plots which one treated with suspension of tea seed cake (3 kg/rai ; control 1) and another was untreated (control 2). In each plot contained 30 different sizes of snails. The results showed that in 48 hours after treated with soapberry and tea seed cake, the percentage mortality of snails were more than 50 and significantly to untreated plot In 15 days after treated with soapberry...
