Virtual Cotton Pesticide Visualisation

Unprotected plant parts, shown as green, accumulate until a pesticide spray is applied. Plant parts protected by pesticide are shown as red. It is unrealistically assumed that the spray is completely efficient and that all plant parts present at the time of the spray become fully protected. New, unprotected, plant parts are produced by on-going growth, causing a steady increase in the percentage surface area of the plant which is not protected. It is assumed, also unrealistically, that the pesticide suddenly stops being effective 5 time steps after it was applied. Future versions of this simulation will use field data to specify the pesticide doses received and the rates of pesticide decay for plant parts in different positions in the canopy.
