“…In our study, seed treatment with NO 60EC (C) and imidacloprid increased the seed germination and seedling vigor in okra. Our findings coincide with previous findings that seedling emergence was more rapid in seeds treated with fungicides/insecticide mixtures than untreated seeds (Ahmed et al 2001). All the insecticidal seed treatment recorded significantly higher amounts of phenol in the host plants compared to untreated control.…”

Insecticidal seed treatment is an alternative method to spray and granular applications. It can protect the crop right from germination to reproductive stage. Recurrent use of chemical insecticides destabilizes the ecosystem and enhances the development of resistance in pest population. Use of biopesticides like neem oil (NO) is a promising one in this situation. Two field experiments were conducted to test the efficacy of NO as a seed dresser (20 ml kg À1 ) and the effect was compared with systemic chemical insecticides imidacloprid (7 g kg À1 ) and carbosulfan (7 g kg À1 ) and Pseudomonas fluorescens (10 g kg À1 ). Field studies revealed that the neem oil 60EC (C) (NO 60EC (C)) recorded minimum population of sucking pests Leafhopper-Amrasca biguttula biguttula Ishida and Aphids-Aphis gossypii Glover (Homoptera: Cicadellidae and Aphididae), i.e., below the ETL (2 number per leaf) up to 45 days after sowing and provided better yield compared to control. Although the systemic chemical insecticide imidacloprid performed better by recording 11,280 and 11,580 kg ha À1 of marketable fruit yield, NO 60EC (C) also recorded about twofold increase in marketable fruit yield 11,000 and 10,620 kg ha À1 , respectively, in 2001 and 2002 experiments. Results of this study suggest that NO could be used as a potential seed dresser for managing sucking pests in okra.

“…Imidacloprid is a general-use pesticide used worldwide for crop-, fruit-, and vegetable pest control, termite control, and flea control in dogs and cats (Ishii et al, 1994;Cox, 2001). It is most commonly used on rice, cereal, maize, potatoes, vegetables, sugar beet, fruit, cotton, hops, and turf Huijbregts, Gijssel, & Heijbroek, 1995;Ahmed, Kanan, Inanaga, Ma, & Sugimoto, 2001;Dikshit & Lal, 2002;Kuhar, Stivers-Young, Hoffmann, & Taylor, 2002).…”

The aim of this work was to report on imidacloprid [IUPAC name 1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine] residues in some vegetables, fruits, and water samples collected from the West Bank, Palestine, in 1998 and 1999. Imidacloprid and its derivatives in the study samples were extracted by methanol/ water and oxidized into 6-chloronicotinic acid and subsequently derivatized into 6-chloronicotinic acid trimethylsilyl ester before being determined by GC/MS. Imidacloprid residues were detected in more than half of the analyzed samples. The highest and lowest imidacloprid concentrations were found in eggplant (0.46 mg/kg) and green beans (0.08 mg/kg), respectively. An increase of 11-120% in imidacloprid concentration in the 1999 samples was observed when compared with those of 1998. This may suggest imidacloprid accumulation in the soil and/or increased use by local farmers. The imidacloprid residue concentrations in several crops were found to exceed the CODEX maximum residue limit.

“…Foliar insecticides are a common, simple, and effective means of controlling the wheat aphids (Pike et al, 1993). The insecticides (e.g., Acetamiprid and Imidacloprid) are most commonly used insecticides controlling wheat aphids in many countries including China (Nakayama et al, 1997;Flückiger et al,1992;Ahmed et al, 2001). The spraying time of Zn application is very important to achieve higher grain Zn concentration of wheat.…”
