“…and Argentine stem weevil (Listronotus bonariensis) in pasture, maize and brassica, respectively. It is also reportedly used for aphid control in potatoes (Szeto et al 1990) and larvae of carrot fly (Psila rosae) (Suett and Jukes 1997). With the total production of 4800 MT of phorate in India (http:// www.indiainfoline.com/sect/chag/ch12.html), the persistence of this toxic (LD 50 ¼ 2 ppm) insecticide (Hassall 1990) in the environment poses a serious concern.…”

“…The incessant exposure of soil microorganisms to such toxic chemicals may result in the development of enhanced detoxification potential, and acquisition of new traits (Felsot et al 1981). Earlier studies have demonstrated the microbial transformation of phorate into phosphodithioate sulphoxide and phosphodithioate sulphone (Chapman et al 1982;Szeto et al 1990). However, to understand how this and other agrochemicals works in soil ecosystem, it is important to know the extent and kinetics of detoxification in specific environmental niches in different geographical regions.…”

Phorate [O,O-diethyl-S S-(ethylthio)methyl phosphoradiothioate] degrading bacteria were isolated from agricultural soil and characterized based on their morphological and biochemical characteristics. The selected isolates PS-1, PS-2 and PS-3 were presumptively identified as Rhizobium, Pseudomonas and Proteous species, respectively. The HPLC analysis of phorate in bioaugmented soil revealed its complete disappearance within 40 days. The degradation isotherms of the isolates PS-1, PS-2 and PS-3 suggested time-dependent disappearance of phorate following the first order rate kinetics at the corresponding rate constants of 0AE04, 0AE05 and 0AE04 days )1 . Besides, the isolates concurrently exhibited substantial phosphate solubilization, indole acetic acid, and siderophore production. The isolate PS-3 also showed anti-fungal activity against a phytopathogen Fusarium oxysporum. As a result of the multifarious biological properties, the isolates have been suggested to be important bioresource for efficient bioinoculant development.

L'influence de la pyrale du maïs, Ostrinia nubilalis (Lepidoptera: Pyralidae) sur le rendement des pommes déterre (Solanum tuberosum 'Russet Burbank') a été évaluée à deux localités de l'île du Prince Edouard en 1989 et 1990. À Summerside, le nombre moyen de larves par tige n'a pas excédé 0,19 pour ces deux années, et aucune différence significative de rendement n'a été trouvée entre les parcelles-témoins non traitées et les parcelles protégées avec le Bacillus thuringiensisvar. kurstaki (B.t.k.). À Tryon en 1989, une moyenne saisonnière de 1,16 larves par tige a réduit les rendements totaux et vendables de 7,5 et 8,8% respectivement, par rapport aux parcelles protégées par le B.t.k. Une tendance similaire quoique non significative a été observée en 1990 à ce même endroit. Le niveau plus élevé de dommages causés par la pyrale du maïs aux pommes de terre cultivées à l'île du Prince Edouard, par rapport aux cultures de régions plus au sud, peut être dû au plus long intervalle d'attaque. À l'île du Prince Edouard, le seuil d'action pour la pyrale du maïs sur les pommes déterre semble se situer entre 0,11 et 0,30 masse d'oeufs par tige.The effects of the European corn borer, Ostrinia nubilalis [Lepidoptera: Pyralidae], on yield of 'Russet Burbank' potatoes (Solanum tuberosum) was investigated at two sites in Prince-Edward-Island in 1989 and 1990. At Summerside, the mean number of larvae per stalk did not exceed 0.19 in either year, and no significant differences in yield were found between untreated plots (check) and plots protected with Bacillus thuringiensis var. kurstaki (B.t.k.). At Tryon in 1989, a seasonal average of 1.16 larvae per stalk reduced total and marketable yields by 7.5% and 8.8%, respectively, compared to plots protected with B.t.k. A similar but not statistically significant trend was observed in 1990 at this site. The higher degree of damage by the European corn borer to potatoes grown on P.E.I., relative to crops grown in more southernly locations, may be due to the longer interval of attack. On P.E.I., the action threshold for the European corn borer on potatoes appears to be between 0.11 and 0.30 egg masses per stalk

“…Similarly, with other microbial species, identified phorate metabolites included phosphodithioate sulphoxide, phosphodithioate sulfone, diethyl dithiophosphate, triethyl dithio-phosphate, diethyl disulfide, formaldehyde and hydrogen sulfide (Szeto et al, 1990;Hong and Pehkonen, 1998;Hong et al, 2000;Singh et al, 2003;Kadam and Gangawane, 2005). Thus, different microbial species resulted in the different degradation products some of which are far more toxic than the parent compound (Henderson et al, 2004).…”
