Duration:1 Semester
Credits: 5
NFQ Level:Advanced
Field of Study: Agriculture
Valid From: Semester 1 - 2018/19 ( September 2018 )
Module Delivered in 1 programme(s)

Module Description: Exploration of crop pathology describing the significant threatening pathogens and pests of agriculture crops in light of modern biotechnological and sustainable used pesticide and other based technologies.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Critique the main agricultural crop pathogens and their lifecycles
LO2 Explore the impact of crop pathogenicity on agronomic and post harvest crop systems
LO3 Evaluate growing or post harvest crops to discern between the presence of crop disease, pestilence or disorders
LO4 Debate options of crop protection measures using sustainable use directive criteria regarding pesticides, advanced crop breeding and cultural solutions
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Co-requisite Modules

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.

Plant disease forecasting.
Crop pathogens
Crop epidemiology. Discerning between symptoms and signs. Application of Koch's postulates. Broad and host specific pathogens, Cereal crops Mildews (Powdery and Downy), spots (leaves), rusts, smuts, general crops blight, wilts,cankers, sooty moulds, scabs, galls, cereal, bulb, corm, tuber, flower, fruit, vegetable, stem, leaf and bud rots.. Post harvest disease of agricultural crops.. Virus and virus like diseases, vectors and lifecycle. Pathogenicity recognition. Visual crop problem identification academic resources. Notifiable diseases. Control of environmental conditions to control disease.
Crop pestilence
Pests of forage grasses, cereals, Brassica, potato and other field crops: Slugs and snails; Aphids; Nematodes, Eelworms, Globodera, Ditylenchus, Aphelenchoides, Meloidogyne, Heterodera; Thrips (Thrips, Kathothrips, Heliothrips; Caterpillars; Mealybugs (Pseuadococcus, Trionymus); Mites (Tetranychus, Steneotarsonemus, Cecidophyopsis, Rhizoglyphus, Birds; mammals; sawfly (Hoplocampa, Nematus); Capsid bugs (Calocoris); Psyllids (Psylla); Scale insects (Pulvinaria, Chionapsis).
Fungicides groups. Hygene, disinfection, prophylaxis, chemotherapy. Protectant, preventative or contact fungicides (Chlorobenzenes, Pthalonitriles, Dithiocarbamates, Organotin, Sulphur). Eradicant, curative or systemic fungicides and insecticides (MBC's, DMI group, Morpholine group, Organophosphates and phosphonates, Dicarboximides, Phenylamides). Safe fungicide and insecticide use. Herbicides groups. Contact, systemic, selective, per-emergence, post-emergence, organic industry herbicides. FRAC. Sustainable use directive best practice of use of pesticides.
Crop genetics for resistance
Crop traits and mechanisms conferring resistance to pathogens and pests of grasses, cereals and other agricultural crops. Induced resistance. Integrated crop biotechnological breeding and disease/ pestilence control. Programmed cell death mechanisms. Solid resistance. Systemic aquired resistance. Advanced agricultural crop resistance case examples.
