Graham Matthews graduated at Imperial College, London as an entomologist, who had also included Chemistry in 1957. Immediately I did a visit to Nigeria travelling on a cargo ship and on a different cargo ship to examine the insects on the cargoes during the return to the Uk In 1958 I went to Southern Rhodesia (now Zimbabwe) and Nyasaland (now Malawi) to do research on control of insect pests of cotton crops.
In 1967, I returned to Imperial College, but was seconded to Malawi in 1968 to follow up previous research there, which involved a study on ultra-low volume spraying of cotton, as farmers had difficulty obtaining enough water to spray with a knapsack sprayer.
In 1972, I returned to Imperial College and remained at Silwood Park campus until I retired in 2001. In 1974 I obtained my PhD and later received a DSC. Over this period I did teaching, including special courses for overseas visitors and research on Pesticide Application and supervised students doing their Doctorate. The research unit was known as the International Pesticide Application Research Centre (IPARC). I also did tests of different sprayers for WHO in relation to controlling mosquitoes, and since retirement did some training courses for WHO in four countries, namely Mexico, Gambia, India and Vietnam..
I visited numerous countries, including Brazil, China, Colombia, Egypt, Kenya, South Africa, Sudan, Tanzania, Philippines, Thailand Turkmenistan and Uzbekistan, to advise on crop protection. Visits to certain countries, including Australia, Cameroon, Ethiopia, India, Malaysia, Nigeria, Pakistan, USA, Canada, Trinadad, Jamaica and Zimbabwe included participation in training courses on pesticide application.
I have published several books between 1979 and 2022, notably Pesticide Application Methods (4th Edition 2014, with the 5th edition that should be ready to be published soon), Pesticides, Health, Safety and the Environment (2nd edition 2016), Pest Management (1984), Cotton Pests and their Management (1989), Integrated Vector Management (2011), A History of Pesticides (2018), and Pest Management in Cotton: A Global Perspective (2022). I have also written articles for journals and contributed a chapter to several other books.
I am now an Emeritus Professor.
