Disease Resistance In Fruit And Vegetables
There are a number of lines of defence against pests (that is, those animals that cause damage to the plants we grow) and diseases in the organic garden, principal among these being the practice of good husbandry, creating healthy soil and ensuring high standards of garden hygiene. But no matter how diverse and healthy the garden eco-system may be, there will always be a degree of disease and pest presence. In many ways, some level of pathogen population in the garden can be not only acceptable but desirable as they are indicative of a generally healthful and diverse environment, and add to the overall robustness of the system as an immunity to such detrimental influences will build up, particularly in a balanced polycultural regime. Indeed, most of the plants we grow will tend to be selected because they are trouble free, and those that are more susceptible to attack will have fallen by the wayside over time. However, most farmers find it unacceptable that the food crops they grow are damaged by pests.
For these crops there has been considerable research and selective breeding carried out in order to find cultivars that are resistant or immune to pest and disease damage. Breeding for plant disease resistance generally has involved finding suitable genetic material amongst existing stocks or in the wild, which is then incorporated into commercial varieties.

Famous quotes containing the words disease, resistance, fruit and/or vegetables:
“Is not disease the rule of existence? There is not a lily pad floating on the river but has been riddled by insects. Almost every shrub and tree has its gall, oftentimes esteemed its chief ornament and hardly to be distinguished from the fruit. If misery loves company, misery has company enough. Now, at midsummer, find me a perfect leaf or fruit.”
—Henry David Thoreau (18171862)
“The resistance we make to our passions is due to their weakness, not our strength.”
—François, Duc De La Rochefoucauld (16131680)
“I am a rose of Sharon, a lily of the valleys. As a lily among brambles, so is my love among maidens. As an apple tree among the trees of the wood, so is my beloved among young men. With great delight I sat in his shadow, and his fruit was sweet to my taste.”
—Bible: Hebrew, Song of Solomon 2:1-3.
“A woman who writes feels too much,
those trances and portents!
As if cycles and children and islands
werent enough; as if mourners and gossips
and vegetables were never enough.”
—Anne Sexton (19281974)
