Reference excerpt

Inter-Regional Research Project Number 4 (IR-4 Project, also referred to as the Minor Crop Pest Management Program) is an agricultural program of the USDA Cooperative State Research, Education, and Extension Service which has been in effect since 1963. IR-4 works in coordination with the Environmental Protection Agency to assist in the collection of residue and efficacy data in support of the registration or reregistration of minor use pesticides and the determination of tolerances for residues of minor use chemicals in or on raw agricultural commodities. IR-4's mission is to facilitate registration of sustainable pest management technology for fruits, vegetables, ornamental plants, and other "minor" crops, i.e. high in value but not widely grown in the United States. While most of the minor uses investigated are small enough that it is not profitable for private business to establish the acceptability of a pesticide for individual specialty crops, collectively the specialty crops covered by the project make up almost half of U.S. agricultural crop production and over $40 billion in sales.

Worked examples

Example 1 — a first encounter with Inter-Regional Research Project Number 4

Start with the simplest possible case. Write down what Inter-Regional Research Project Number 4 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Inter-Regional Research Project Number 4 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Inter-Regional Research Project Number 4 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Inter-Regional Research Project Number 4

In research: Inter-Regional Research Project Number 4 appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Inter-Regional Research Project Number 4 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Inter-Regional Research Project Number 4 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture stubs, Pesticides in the United States, United States Department of Agriculture, so understanding it makes those chapters shorter.
In everyday life: Look for Inter-Regional Research Project Number 4 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
