The Economics Of Integrated Pest Control In Irrigated Rice

As a result of the green revolution, the use of yield-increasing inputs such as fer tilizer and pesticides became a matter of course in irrigated rice farming in Southeast Asia. Pesticides were applied liberally, both as a guarantee against crop failure and as a means of fully utilizing the existing yield potential of the crops. However, since outbreaks of pests, such as the brown planthopper (BPH) or the tungro virus, continued to occur despite the application of chemicals, a change of approach began to take place. It is now being realized more and more in Southeast Asia that crop protection problems cannot be resolved solely by the application of chemicals. In the past several years, increasing efforts have there fore been made to introduce, as a first step, supervised crop protection, leading gradually to integrated pest management (Kranz, 1982). Although the crop protection problems naturally differ in the different devel oping countries in Southeast Asia, the economic situation prevailing in these countries can nevertheless be regarded as an important common determinant: pesticide imports use up scarce foreign currency and thus compete with other imports essential to development. For the individual rice farmer, the problem is basically the same: his cash funds are limited and he must carefully weigh whether to use them for purchas ing pesticides, fertilizer or certified seed. In view of this constraint, it is becom ing necessary to abandon the purely prophylactic, routine calendar spraying and instead, employ critically timed and need-based pesticide applications.

ntegrated pest management (IPM) provides a long-term strategy for minimizing losses caused by pests, with as little cost to the grower and disruption of the environment as possible. Written by a collaboration of experts in the field, this detailed manual is designed to help growers apply IPM principles in managing their rice crops. What's Inside? Special sections on crop growth and development and general management practices offer vital background information on using IPM strategies. The chapter on “Managing Pests in Rice” provides a detailed chart of management considerations that will help you plan your IPM program and predict or prevent potential problems before they occur. Vibrant and colorful photographs and descriptions fill the pest sections (weeds, invertebrates, diseases, and vertebrates) to help identify pests and pest damage. An informative glossary is available for looking up definitions of unfamiliar terms. What's new in the 3rd Edition? New exotic pest discussionNew detecting, confirming, and managing herbicide resistance sections21 new photos added for diseases, weeds, and vertebratesColor illustrationsNew life cycle illustrations for each disease3 new diseases and 4 new weeds, including Bakanae, Rice Blast, and Red Rice

The book begins by establishing an economic framework upon which to apply the principles of IPM. Then, it looks at the entomological applications of economics, specifically, economic analyses concerning chemical, biological, cultural, and genetic control tactics as well as host plant resistance and the cost of sampling. Lastly it evaluates whether the control provided by a traditional IPM system is sufficient, or if changes to the system design would yield greater benefits.

Integrated Pest Management – Dissemination and Impact, Volume 2 is a sequel to Integrated Pest Management – Innovation-DevelopmentProcess, Volume 1. The book focuses on the IPM systems in the developed countries of North America, Europe and Australia, and the developing countries of Asia, Latin America and Africa. One of the major impedimentsin the dissemination and adoption of the IPM innovation is the complexity of the technology and reaching the vast population of farmers especially in the developing countries. The IPM-innovation development process is incomplete without the diffusion and adoption of IPM methods by the end users, and through its consequences. In spite of all the efforts in the developed and developing countries, the adoption of IPM is still low with few exceptions. The book covers the underlying concepts and methodologies of the diffusion of innovation theory and the program evaluation; and reviews the progress and impact of IPM programs implemented in the industrialized, the green revolution and the subsistence agricultural systems of the world. Forty-four experts from entomology, plant pathology, environmental science, agronomy, anthropology, economics and extensioneducationfromAfrica, Asia, Australia, Europe,NorthAmerica and South America have discussed impact of IPM with an interdisciplinary perspective. Each one of the experts is an authority in his or her eld of expertise.

"Concerns about the sustainability of conventional agriculture have prompted widespread introduction of integrated pest management (IPM), an ecologically-based approach to control of harmful insects and weeds. IPM is intended to reduce ecological and health damage from chemical pesticides by using natural parasites and predators to control pest populations. Since chemical pesticides are expensive for poor farmers, IPM offers the prospect of lower production costs and higher profitability. However, adoption of IPM may reduce profitability if it also lowers overall productivity, or induces more intensive use of other production factors. On the other hand, IPM may actually promote more productive farming by encouraging more skillful use of available resources. Data scarcity has hindered a full accounting of IPM's impact on profitability, health, and local ecosystems.
