Seed treatment as a method of local application of pesticides in precise agriculture reduces the amount of pesticides used per unit area and is considered to be the safest, cheapest and most ecologically acceptable method of protecting seeds and young plants from pests in the early stages of their development. With the introduction of insecticides from the neonicotinoid group in the mid-1990s, the frequency of seed treatment increased. Due to suspected negative effects on pollinators, most of these insecticides are banned in the European Union. The ban has therefore led to a reduction in the number of active substances approved for seed treatment and to an increased re-use of active substances from the group of pyrethroids as well as other organophosphorus insecticides, which pose potentially very serious risks, perhaps even greater than those of the banned neonicotinoids. The objective of this review is to analyze the advantages and disadvantages of seed treatment and the potential role of insecticide seed treatment in reducing the negative impact of pesticides on the environment. The main disadvantage of this method is that it has been widely accepted and has become a prophylactic protective measure applied to almost all fields. This is contrary to the principles of integrated pest management and leads to an increased input of insecticides into the environment, by treating a larger number of hectares with a lower amount of active ingredient, and a negative impact on beneficial entomofauna. In addition, studies show that due to the prophylactic approach, the economic and technical justification of this method is often questionable. Extremely important for a quality implementation are the correct processing and implementation of the treatment procedure as well as the selection of appropriate insecticides, which have proven to be problematic in the case of neonicotinoids. The ban on neonicotinoids and the withdrawal of seed treatments in oilseed rape and sugar beet has led to increased problems with a range of pests affecting these crops at an early stage of growth. The results of the present studies indicate good efficacy of active ingredients belonging to the group of anthranilic diamides, cyantraniliprole and chlorantraniliprole in the treatment of maize, soybean, sugar beet and rice seeds on pests of the above-ground part of the plant, but not on wireworms. Good efficacy in controlling wireworms in maize is shown by an insecticide in the naturalites group, spinosad, but it is currently used to treat seeds of vegetable crops, mainly onions, to control onion flies and flies on other vegetable crops. Seed treatment as a method only fits in with the principles of integrated pest management when treated seeds are sown on land where there is a positive prognosis for pest infestation.

Arthropod Pests

Disease and arthropod pests are a continual problem for greenhouse vegetable production. These problems range from minor infestations to major disease or arthropod pest outbreaks that can destroy an entire crop. In Ontario, in the past, the major management strategy was pesticide control. However, many plant pathogen, insect and mite pests are resistant to registered pesticides and few new pesticides are being developed. Alternative control strategies exist or are being developed for most major pests. This review describes the current status of pesticide, cultural and biological control of disease and arthropod pests of greenhouse vegetables in Ontario and discusses the future possibilities for the integration of pest management practices utilizing plant resistance, nutrition, environment and biological control agents into an expert system approach. Key words: Vegetable (greenhouse) crops, integrated pest management

The bio-efficacy of imidacloprid seed treatment against leafhopper and thrips of groundnut was studied during kharif (23rd to 42nd standard week) and summer (5th to 23rd standard week) cropping seasons of 2010 and 2011. The six different concentrations viz., 0.5, 1.0, 2.0, 3.0, 4.0 and 5.0 g a. i. kg-1 were tested for their bio-efficacy. A modified sweep net method was followed to record the leafhopper and thrips populations. Seed treatments with imidacloprid @ 2.0 to 5.0 g a. i. kg-1 were found most effective in reducing the insect population. However, seed treatment with imidacloprid @ 2.0 g a. i. kg-1 may be included in integrated pest management (IPM) package for groundnut from environmental safety point.

AbstractThe glasshouse whitefly (Trialeurodes vaporariorum Westwood) is a polyphagous arthropod pest that is of particular detriment to glasshouse grown tomato (Solanum lycopersicum) across temperate regions of the world. Control of whiteflies with synthetic pesticides has resulted in the evolution of resistant genotypes and a reduction in natural enemies, thus highlighting the need for environmentally sound control strategies. Volatile organic compounds (VOCs) offer an environmentally benign alternative to synthetic chemical sprays and this study explored the use of VOCs as insect repellents and plant defence elicitors to control whiteflies on tomato in a commercial glasshouse setting. Limonene in the form of a volatile dispenser system was found to successfully repel whitefly from the target crop and increased fruit yield by 32% during a heavy whitefly infestation. Analysis of tomato herbivore induced plant volatiles (HIPVs) led us to select methyl salicylate (MeSA) as the plant elicitor and application of MeSA to un-infested tomato plants was found to successfully reduce whitefly population development and increase yield by 11%, although this difference was marginally statistically significant. Combination of these two methods was also effective but whitefly abundance in combined plots was similar to the standalone limonene treatment across the course of the experiment. All of the VOC based control methods we used had a negative impact on whitefly performance, with more pronounced effects during the first few weeks of infestation. In subsequent laboratory experiments, we found elevated peroxidase (POD) activity and a significant increase in TPX1 and PR1 transcripts in MeSA treated plants. This led us to deduce that MeSA immediately induced plant defences, rather than priming them. We did however see evidence for residual priming, as plants treated with MeSA and infested with whiteflies produced significantly higher levels of POD activity than whitefly infestation alone. Despite the fact that our treatments failed to synergise, our methods can be optimised further, and the effectiveness of the standalone treatments is promising for future studies. In particular, our repellent limonene dispensers were extremely effective at deterring whiteflies and offer a low economic cost and easy to implement whitefly control option. The methods we have used here could be incorporated into current integrated pest management (IPM) systems, a sustainable approach to pest control which will be central to our efforts to manage whitefly populations under glass in the future.

Significant Difference

In the present study, documentation of farmer’s knowledge on Integrated Pest Management (IPM) was carried out in Rupandehi district during the year 2016. The objective of this paper is to assess the knowledge of farmers about IPM and its effectiveness in this district. It was carried out by conducting semi-structured interview with the participants of IPM FFS, vegetable growing farmers, stakeholders and local people with the help of standard questionnaire, Focus Group Discussion (FGD) and key informant interview. The IPM program is found to be conducted by an international non-government organization viz. Food and Agriculture Organization (FAO) and government organizations viz. Plant Protection Directorate (PPD), Agronomy Development Directorate (ADD) and District Agriculture Development Organization (DADO) through Farmer’s Field School (FFS) in this district. In total forty IPM FFS was conducted from 1998 to 2015 which provided training about IPM in rice and vegetable crops to 1057 farmers in which 393 were male and 664 female. Although a significant difference has been found in the knowledge about the amount of pesticide used, biological method of pest control for IPM by FFS participant and nonparticipant farmers, it is not observed in their behavior during the cultivation of crops in the farm. The result showed that only 5% of participants of Farmer’s Field School (FFS) are following IPM practices in their own farm after taking training. Int. J. Appl. Sci. Biotechnol. Vol 5(2): 237-242
