On the conceptual basis of crop loss assessment: the threshold theory
TLDR
This paper focuses on the individual farmer as a decision maker and the services the pathologist can render him; it deals with tactical decisions.Abstract:
Crop loss has become so broad a subject that a comprehensive review of the topic would be limited to generalities that are rather well known by now (2, 11-13,31,39,88). For this reason, I have chosen to limit this review to the exploration of a single theme, the threshold theory, which I feel confident discussing because of my experience. This paper focuses on the individual farmer as a decision maker and the services the pathologist can render him; it deals with tactical (17, 101) decisions.read more

Quantification and modeling of crop losses: a review of purposes.
TL;DR: This review considers the cascade of events that link injuries caused by plant pathogens on crop stands to possible (quantitative and qualitative) crop losses (damage), and to the resulting economic losses, and proposes a framework linking different types of knowledge on crop loss to a range of decision categories.

Rice Pest Constraints in Tropical Asia: Quantification of Yield Losses Due to Rice Pests in a Range of Production Situations
TL;DR: In this article, a series of experiments were conducted where a range of injuries due to rice pests (pathogens, insects, and weeds) was manipulated simultaneously with a variety of production factors (fertilizer input, water supply, crop establishment method, variety).

Assessment of plant diseases and losses
TL;DR: Only by disease-loss appraisal is it possible to determine the economic loss due to different amounts of disease, and loss estimates may achieve new significance by providing evidence that will justify or condemn the use of fungicides to control epidemics.

Economics of Decision Making in Pest Management
J. D. Mumford,G. A. Norton +1 more
TL;DR: The economics of decision making in pest management is not just concerned with the dollars and cents of pest damage and control but with the goals and behavior of those who make pest management decisions.
