Crop diversity are all susceptible to a single fungus, "Fusarium oxysporum" (Panama disease); large areas of the crop were destroyed by the fungus in the 1950s. 'Gros Michel' has been replaced by the current main banana on the market, the 'Cavendish', which in turn is (2015) at risk of total loss to a strain of the same fungus, 'Tropical Race 4'. Such threats can be countered by strategies such as planting multi-line cultivars and cultivar mixes, in the hope that some of the cultivars will be resistant to any individual outbreak of disease. The implications of crop diversity are at both local
Crop scouting locate and tag crop issues, visualize them on an aerial map and make decisions for site-specific treatments. Before starting any actual scouting, preparation is essential to provide accurate information in an efficient manner. Crop scouting is a Integrated pest management strategy that looks at many different aspects of crop production, not just any single pest or problem. Scouts must be actively observing environmental conditions, beneficial insects, pest insects, diseases, weeds, crop growth stage, and the general health of the crop in question to get a complete picture of any problems. Since field and landscape characteristics affect pest distribution, symptom expression,
