4.1.1 Identification of Disease-Free Areas for Healthy Seed Production
An important consideration for seed production is to select the site and the field where the climatic conditions are favourable for the plant to grow, flower, and set seed. Besides, it is also important to know about the past history of the field such as previous crops cultivated, weed populations, predominant diseases, and other intrinsic factors for successful disease-free seed production. For example, chickpeas should not be planted on the land on which lucerne was previously grown, as Phy...
4.1.2 Time of Sowing
Altering the sowing or planting date can help to reduce the disease outbreaks by avoiding the weather conditions favourable for pathogens to grow, multiply, and infect the crop. Prolonged wet weather favours the occurrence of many diseases, e.g. downy mildew requires prolonged high moisture to cause infection. Chickpea (Cicer arietinum) root rot caused by Rhizoctonia spp. intensifies if the crop is sown immediately after rainfall. Early maturing varieties of wheat and pea are able to escape i...
4.1.3 Cultural Practices
The aim of the good cultural practices is to create favourable environmental conditions for crop development, promote good plant health, and limit the spread of plant pathogens, thereby minimizing the disease outbreaks. Some common practices include tillage, removal, and destruction of diseased crop residues or debris, eradication of alternate and collateral hosts, cultivation of non-host crops, selection of disease-free seeds, maintenance of appropriate isolation distances, timely rouging of...
Seed certification is a regulatory management practice for disease-free seed production and to reduce the seed-borne infection. Seed certification ensures that the seed has certain set standards and the quality and history of each seed lot are evident and may be traced. Seed certification procedures are established to maintain the standards of puri...
Plant quarantine is a legislative procedure to exclude the plant pathogens from invading into an area where they do not exist, by monitoring the import and export of plant, seeds, grafts, planting material, or equipment to prevent the spread of diseases and pests through these sources. Plant quarantine may, therefore, be defined as ‘Rules and Regul...
Seed treatment refers to an application of physical, chemical, biological, or organic matter(s) to the seed to provide protection against pests and pathogens to germinating seed and seedlings and to improve the establishment of healthy crops. Seed treatment improves the seed quality and manages the seed-borne pathogens. Seed treatment not only bene...
In general, seed certification is a process designed to maintain and make available to the general public continuous supply of high quality seeds and propagating materials of notified kinds and varieties of crops, so grown and distributed to ensure the physical identity and genetic purity.
