Compulsory integrated pest management poses a number of challenges and issues for debate. Some of are discussed with reference to European Union requirements set out in Annex III of Directive 128/2009. Requirements on the use of plant protection products bring with them problems with dose reduction in the light of a resistance prevention strategy, the lack of threshold levels, the necessity of chemical treatments and the limited availability of effective products of biological origin. Use of preventive measures of pest control faces barriers related to profitability and a lack of knowledge on the part of farmers. Challenges to control the system, as well as the fact that some legally enforced rules are not suitable for all crops, seem also to be an issue. © 2019 Society of Chemical Industry 相似文献

Supervised control programs were initiated by the Extension Service in the deciduous orchards of Upper Galilee and the Golan
almost 20 years ago. The integrated pest management (IPM) project on fruit crops and vines, launched as a systematic state-wide
program in 1991, covered 23% of the total acreage at the end of 1996. The program has reached a critical mass and generates
a steady demand for this new kind of advisory service. The project has set the right pattern for intensive and continuous
collaboration among research, extension and grower. The program has been successful in reaching out to growers with the help
of a newly formed group of local and regional pest scouts; the field-level implementation is the responsibility of the extension
system. A reduction of approximately 30% in the use of pesticides has been achieved. The project prepares the ground for environment-friendly
and sustainable cropping systems, generating produce competitive on both the local as well as foreign markets. The program
on indoor vegetables, flowers, herbs and spices initiated in 1992, had to address first the problem of the sweetpotato whitefly.
The field program methodology relies on the establishment of model farms and plots. The model plots are used to examine supervised
control scenarios which could, in turn, be diffused to all growers. A 30-50% reduction in the use of pesticides was achieved
on the model farms. The program represents an integration of supervised control, fully fledged IPM, and biological control
practices. The program on corn and cotton covers the entire acreage under these two crops. The cotton program is supported
by an integrated resistance management component. Three area-wide pest management programs were initiated: in the Arava and
Bet She’ an valleys, and in the Golan. 相似文献

Decision-makers in the protected crop environment face similar pest-management decisions, in economic terms, to growers of field crops or grain store managers. As a result, the principles of economic thresholds, cost: benefit analyses and risk minimisation apply equally to each of these systems. Growers are faced with several general classes of pest-control decisions: the general control strategy to adopt, and then tactical questions such as when to start control and when to stop or change control practices. However, there are a number of aspects of protected crops which require a somewhat different view of the problem. Several economic models for these questions are examined. The high density of protected crops means that a great deal is at risk at any one time. The protected environment reduces uncertainty about losses, but by optimising temperatures and humidities it increases the probability of loss. The feeling of being able to “control” the environment may extend to pests as well, increasing the use of standard pesticide or biocontrol programmes, rather than responsive pest management based on thresholds. The relatively small scale of protected crops, their accessibility for inspection and the high level of management skills involved in their production improve prospects for monitoring and predicting crop levels, insects and diseases, thus reducing uncertainty. However, the high probability of loss may reduce the value of gathering information, and encourage growers to rely on standard prophylactic procedures which allow them to devote management effort to more productive activities, such as marketing. The balance may be shifted towards more information-based decisions in the future to try to avoid excessive pesticide use because of more stringent regulations on pesticide residues and changing market demand for more organic produce. This may affect disease control in particular, where prophylactic biological control is not an option. At the policy level, feedback on environmental impacts to consumers and policy-makers is poor and decisions with expensive implications for the economy and for environmental quality may not be made in an optimal manner. 相似文献

Insecticide resistance management (IRM) is a component of integrated pest management (IPM) that has the goal of forestalling resistance development to all insecticides. Since the advent of the organochlorine insecticides in the 1940s, an average of about one class of insecticide has been lost every 10 years because of resistance. Effective insecticides are necessary for optimum IPM and are too important and too expensive a resource to be lost so rapidly. By adhering to the principles of IPM and utilizing other IPM components such as biological and cultural control, IRM has the potential of conserving the susceptibility of pests to insecticides. Although initial attempts of IRM appear to be successful, it is imperative that research to undergird IRM be greatly accelerated. 相似文献

The foundation of an integrated pest management program involves valid treatment thresholds, accurate and simple monitoring methods, effective natural controls, selective pesticides and trained individuals who can implement the concept. The Integrated Control Concept written by Stern, Smith, van den Bosch and Hagen elucidated each of these points in an alfalfa ecosystem. Alfalfa hay (Medicago sativa L.) has a low per acre value, requires little hand labor and is primarily marketed in the USA. In contrast, fresh market table grape (Vitis vinifera L.) has a high per acre value, requires frequent hand labor operations, suffers unacceptable cosmetic damage and is marketed throughout both the USA and the world. Each of the components of a working IPM program is present in table grape production. Marketing grapes to foreign countries presents special problems with pests considered invasive and where residue tolerances for some selective insecticides are lacking. However, fresh market grape farmers are still able to deal with these special problems and utilize an IPM program that has resulted in a 42% reduction in broad‐spectrum insecticide use from 1995 to 2007.

BACKGROUND: The Southern Nursery Integrated Pest Management (SNIPM) working group surveyed ornamental nursery crop growers in the southeastern United States to determine their pest management practices. Respondents answered questions about monitoring practices for insects, diseases and weeds, prevention techniques, intervention decisions, concerns about IPM and educational opportunities. Survey respondents were categorized into three groups based on IPM knowledge and pest management practices adopted. RESULTS: The three groups differed in the use of standardized sampling plans for scouting pests, in monitoring techniques, e.g. sticky cards, phenology and growing degree days, in record‐keeping, in the use of spot‐spraying and in the number of samples sent to a diagnostic clinic for identification and management recommendation. CONCLUSIONS: Stronger emphasis is needed on deliberate scouting techniques and tools to monitor pest populations to provide earlier pest detection and greater flexibility of management options. Most respondents thought that IPM was effective and beneficial for both the environment and employees, but had concerns about the ability of natural enemies to control insect pests, and about the availability and effectiveness of alternatives to chemical controls. Research and field demonstration is needed for selecting appropriate natural enemies for augmentative biological control. Two groups utilized cooperative extension almost exclusively, which would be an avenue for educating those respondents. Copyright © 2012 Society of Chemical Industry 相似文献

Sufficient hygiene is an important instrument in preventing infestations of glasshouse crops. Since chemical soil sterilization is more and more restricted, soil-steaming and closed growing systems are coming more and more in use. With closed systems, the question of disinfecting the circulating nutrient solution arises. Screens of different mesh are being tested for the exclusion of pests from glasshouse crops. More and more attention is being paid to the influence of the glasshouse microclimate on the occurrence and spread of pests. Various aspects are discussed in relation to temperature, humidity, leaf wetness, radiation, etc. 相似文献

The European corn borer (Ostrinia nubilalis), the Mediterranean corn borer (Sesamia nonagrioides) and the western corn rootworm (Diabrotica virgifera virgifera) are the main arthropod pests in European maize production. Practised pest control includes chemical control, biological control and cultural control such as ploughing and crop rotation. A pest control option that is available since 1996 is maize varieties that are genetically engineered (GE) to produce insecticidal compounds. GE maize varieties available today express one or several genes from Bacillus thuringiensis (Bt) that target corn borers or corn rootworms. Incentives to growing Bt maize are simplified farm operations, high pest control efficiency, improved grain quality and ecological benefits. Limitations include the risk of resistance evolution in target pest populations, risk of secondary pest outbreaks and increased administration to comply with licence agreements. Growers willing to plant Bt maize in the European Union (EU) often face the problem that authorisation is denied. Only one Bt maize transformation event (MON810) is currently authorised for commercial cultivation, and some national authorities have banned cultivation. Spain is the only EU member state where Bt maize adoption levels are currently delivering farm income gains near full potential levels. In an integrated pest management (IPM) context, Bt maize can be regarded as a preventive (host plant resistance) or a responsive pest control measure. In any case, Bt maize is a highly specific tool that efficiently controls the main pests and allows combination with other preventive or responsive measures to solve other agricultural problems including those with secondary pests.

Pymetrozine is the first and only substance from the group of azomethine pyridines, a novel class of insecticides. The spectrum of activity covers sucking pests such as aphids, whiteflies and planthoppers.Tests were carried out in the laboratory and under field conditions to evaluate its impact on beneficial arthropods.In laboratory tests it demonstrated full selectivity against predaceous Coleoptera, Heteroptera, Neuroptera and the predatory mite Typhlodromus pyri.Following a single application at 250/200g a.i./ha on cotton in Egypt and in the USA, the regular sampling of predators over a period of three weeks revealed a similar population development in the pymetrozine and the untreated control plots. On okra, a vegetable crop in Egypt, it suppressed populations of Aphis gossypii with two sprays at 100g a.i./ha for the whole observation period of 23 days. It also allowed the survival of predators.These positive features make pymetrozine an ideal component in situations where sucking pests have to be controlled and natural enemies can play a substantial role as complementary control tools. 相似文献

The uncertainty of pest and disease outbreaks and the associated damage (risk) may limit the adoption of integrated farming systems. This risk can be reduced by preventive practices and by a selective use of pesticides based on monitoring and forecasts. Whether forecasts based on agrometeorological data may reduce risk depends mainly on the strength of the weather dependency of the host and the parasite and whether outbreaks can be forecast accurately and in time to allow control action. Pests for which the weather only sometimes enables an outbreak, or which exhibit long incubation periods, are good candidates for forecasts based on weather. Epidemics of wheat diseases are discussed as an illustration. 相似文献
