“…The alteration of AChE was observed in the cockroach, Periplaneta americana L., at 4 ppm of AZA, (Shafeek et al 2004) and the snail, Limnaea acuminata Lamarck, at 40% and 80% concentrations of neem oil (Singh and Singh 2000). It was also observed that 25 g of distilled water extracts of the botanicals Punica granatum L., Thymus vulgaris L., and Artemisia absinthium L., significantly inhibited the AChE activity of nematodes at 100% concentrations (Korayem et al 1993). Senthil Nathan et al (2008) demonstrated that LC 50 concentrations of AZA significantly inhibited the activity of AChE compared with control.…”

Abstract:A methanolic extract of Artemisia annua was obtained to evaluate its insecticidal activities against the sunn pest (Eurygaster intefriceps). Also, the responses of general esterase (EST), glutathione S-transferase (GST), alkaline phosphatase (ALP), acid phosphatase (ACP), acethylcholinesterase (AChE) to the plant extract were investigated. Topical application of plant extract on adults showed that the mortality was dose-dependent i.e. with increasing of plant extract concentrations more mortality achieved. Esterase and GST activities were increased in the first 24 h post-treatment. However, the enzymes activities were decreased after 24 h until 72 h. The activities of ALP, ACP and AChE in insect body decreased significantly and inhibition was higher along with increasing concentrations of plant extract. Isozyme electrophoresis profiles indicated that responses of isozymes (EST and GST) to plant extract were decreased after 48 h exposure to extract so that some enzymes bands disappeared. The results indicated that the highest concentration of A. annua extract was the most toxic among the four extracts. The decline of the detoxification ability in insects' tissues might be the main reason for the insecticidal activities.

“…Organic amendments are promising solutions to control PPN growth and may influence other beneficial soil organisms (Mcsorley, 1998;Oka, 2010;Lord et al, 2011). In some studies, the use of organic amendments has positively suppressed the levels of nematodes in the soil, and has resulted in increased levels of nematode trapping fungi or other potential predators or parasites of PPN in the same soil (Akhtar and Malik, 2000;Wang et al, 2001;Oka, 2010).…”

An organic product that consists of proprietary blend of fermentation and plant extracts with micronutrients (ACS 5075, Alltech ® , Inc., Nicholasville, KY USA) was evaluated against four strains of entomopathogenic nematodes (EPN): Steinernema feltiae (SB12(1), a wild enviroCORE strain and a commercial form e-NEMA), Steinernema carpocapsae (e-NEMA), and Heterorhabditis bacteriophora. The effects on egg hatching and survival of root-knot nematodes (RKN) were also examined. The sensitivity to the product was tested by estimating mortality and survival of EPN infective juveniles (IJ) after 24-hr treatment with four different concentrations of product (4, 7, 8, and 10%) compared with the control in a 96-well plate. There was no significant difference in survival of IJ with 4% product compared to the control. A twofold reduction in survival was observed when the EPN were exposed to the product at 7%. A 10.5% RKN egg hatching was observed when RKN were exposed to 3% ACS 5075 concentration compared to 100% hatching in the untreated. A significant (p < 0.05) reduction in juvenile survival was observed at 0.5% treatment, however, it dropped to 0 when 1% and above was used for M. javanica. Juveniles did not survive with all treatment concentrations in the case of M. incognita. The improvement in tomato plant growth and development were also observed when plants were treated with 1 and 3% ACS 5075. The product shows potential as a sustainable soil health alternative causing no harm to beneficial nematodes (EPN) at concentrations below 4%, while is promising against plant parasitic nematodes (PPN) and toward plant growth promotion.

“…Similar eff ects were observed a er the application of phytoncides derived from other essentialoils containing plant species, e.g. Allium cepa, A. sativum, Menta spicata, Tagetes erecta, Nigella sativa, and Azadirachta indica (ABO-ELYOUSR et al, 2009) or Thymus vulgaris, Artemisia absinthum and Punica granatum (KORAYEM et al, 1993;LASHEIN, 2002). A er their application, both the health condition of plants and yields improved.…”

ZAHRADNÍKOVÁ HELENA, PETŘÍKOVÁ KRISTÍNA: Nematocid eff ects of watercress (Nasturtium offi cinale R. Br.). Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 1, pp. 233-236 The watercress (Nasturtium offi cinale R. Br.) is o en grown as a forced leaf vegetable rich in vitamins and minerals. Its specifi c taste and curative eff ects result from the presence of mustard glycosides (glucosinolates) that may also show nematocidic eff ects. The aim of this study was to evaluate the eff ect of watercress eluate and juice on tomato plants inoculated with the northern root-knot nematode (NRKN) Meloidogyne hapla. It was found out that a er the treatment of plants with solutions derived from watercress the yield of fruit was highly signifi cantly increased. The highest yield increase (by 96 % to 165 %) was observed in the variant with the highest concentration of watercress extracts (macerate + 200 ml of juice). Although at lower concentrations of watercress solution the increase in yields was also reduced (by 57-118 %), the diff erence was still statistically highly signifi cant. The eff ect of this treatment on the content of vitamin C was similar and the increase was also highly signifi cant and ranged from 24 to 67 %. When evaluating the occurrence of nematodes on roots of tomato plants, the presence of pathogens was equal to zero percent in all treated variants. The treatment with this phytosolution corroborated not only a nematocidic eff ect of watercress but also its positive infl uence on the yield and level of vitamin C in dependence on increasing concentrations of the eff ective agent. It can be therefore concluded that the watercress solution showed a promoting eff ect on tomato plants.watercress, nematocidic eff ects, tomato, yield, vitamin C The watercress Nasturtium offi cinale R. Br. is a member of Brassicaceae family and is cultivated as a perennial, nutritionally valuable and tasty forced vegetable that is popular in a number of countries. It is rich in chemoprotective substances.
