Crop protection.

2021
Abstract Crop protection procedures have existed since the first attempts at early agriculture. While cultivation of a vast range of crops is vital our existence, these same plants are highly attractive to a diverse range of invertebrate and vertebrate pests, and disease pathogens. Competition from weed species also occurs on a worldwide scale.

Natural products in crop protection

Bioorganic & Medicinal Chemistry, 2009
The tremendous increase in crop yields associated with the 'green' revolution has been possible in part by the discovery and utilization of chemicals for pest control. However, concerns over the potential impact of pesticides on human health and the environment has led to the introduction of new pesticide registration procedures, such as the Food ...

Crop protection

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1973
Abstract Crop protection materials and techniques can increase productivity by preventing losses of yield or quality due to invading pests and by increasing the efficiency of men and machines. Spectacular advances have been made during the last 40 years in the availability of new highly active and relatively efficient chemicals which ...

On the usefulness of mathematics in crop protection [PDF]

open access: possible, 2022
It is acknowledge that economically important crops are more and more damaged by pests and diseases. This is partly due to Climate change but also to international trades that favor the transportation of pests, and diseased seeds or plants. For instance Tephridit fruit flies (which damage fruit and other crops) have already spread du to warmer climate.
