Gce Model Questions Vol1 2017 Agricultural Science Question 12
Practice objective / multiple choice question 12 from the 2017 Gce Model Questions Vol1 Agricultural Science examination.
A wheat field of 5 ha shows rectangular brown leaf lesions 2-4 cm long with a yellow halo. Laboratory analysis identifies a wind‑dispersed fungus that produces conidia. The disease has a latent period of 7 days and an infectious period of 14 days. The initial infected area is 0.1 ha and the basic reproduction number \(R_{0}\) is 2.5 per infectious period. Assuming the infected area multiplies by \(R_{0}\) at the end of each infectious period and that there is no overlap, calculate the percentage of the field that will be infected after 28 days.
