Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to internatio5/5(1). Seed Fields – Pre-harvest burndown of weeds may be necessary in seed production to keep those weed seeds (especially noxious weeds) out of the seed. Let’s talk about an old myth that says something like, “If you spray weeds before the seed is completely made, you might just get lucky and hurt the germination on them.”.

Information about losses is needed to monitor the effects of pests and diseases on crop production, in individual countries and worldwide, important for food policy and economic reasons; to make decisions and allocate resources on the study, Cited by: Grains may be lost in the pre-harvest, harvest, and post-harvest stages.
Pre-harvest losses occur before the process of harvesting begins, and may be due to insects, weeds, and t losses occur between the beginning and completion of harvesting, and are primarily caused by losses due to shattering.
Introduction. Agriculture is the mainstay of the Ethiopian economy (Bezabih and Hadera, ).The country has highly diversified agro-ecological conditions for the production of different cereal, legumes and horticultural crops (Bekele,Milaku, ).More than 85% of its population is engaged in small scale agricultural production as a major means of livelihood Cited by: Pre-harvest losses.
They occur before the harvesting process begins and may be due to such factors as insects, weeds, or diseases afflicting crops. Harvest losses. They occur during the harvesting process and may be due to, for example to shattering and shedding of the grain from the ears to the ground.
Post-harvest losses. They occur during File Size: 2MB. The crops should be free from Insects and other pests, thus creation of new wounds and disease can be avoided.
Hot water and hot air treatment help to reduce further spread of the disease. Chemical control. Post-harvest diseases may be controlled by the application of thiabendazole, dichloran, dosa-ash, etc. The Role of Post-harvest Management in Assuring the Quality and Safety Horticultural Crops 1 Although minimizing post-harvest losses of already produced food is more sustainable than increasing production to compensate for these losses, less than 5 percent of theFile Size: KB.
