Potato diseases and their management PDF

There are many diseases that affect potato tubers, so as you sort through your potato harvest each year, take a moment to check for disease symptoms. Proper identification will help you decide which tubers will store well and which should be sold as tablestock, and will give you a better idea of which soil-borne diseases are present in your fields, improving your future crop rotations Introduction to Potato Diseases and Pests. Are you growing potatoes on large scale? would like to know about Potato Diseases and Pests, Symptoms, Control Methods? the read the following. The potato is the most popular common crop in India.

disease control and harvesting. Choosing a suitable field, soil-type and place in the crop rotation is an important first step to producing potatoes profitably. Potatoes can be grown across a wide range of soil types and should not be grown more than one year in four in a rotation, otherwise potato cyst eelworm may cause a problem come from disease-infested seed stock and can be con-trolled by a fungicide dip before bedding seed roots. Nematodes can come from infested plant-growing beds or infested soil. Fields known to be infested with nematodes or other sweet potato diseases should be avoided. A 3 to 5-year rotation should be practised. Soft rots and other storage disease Because of its nutritional values, the potato is a well-balanced diet for developing countries. Many of weeds, pests, and diseases attacks on potato crop and leads to major yield loses. There is a brief introduction to potato weeds, pests, diseases, and their management.

Organically managed potato fields often follow a longer rotational strategy utilizing green manures and other crops specifically chosen for soil improvement and pest and disease management (Seaman 2015). Cattle often graze green manures, and biologica Pest management methods will vary among individuals according to their tolerance of the pest, the damage and a basic philosophy about buds, flowers, stems and even roots. Plant growth may be stunted. Aphids may also transmit viral diseases like potato leaf roll virus. Aphids excrete a shiny, sticky substance called honeydew that can be seen.

Pests and diseases have continued to affect production of crops and have a serious impact on the economic output of a farm. Farmers need to vary their management methods depending on the crops they grow and the pests or diseases they are susceptible to, since they affect crops differently.

  1. The prevalence of virus diseases is known in many different crops, but the magnitudes of yield loss have not been estimated for all. However, some estimates of crop loss are available for a few serious diseases ().Tospovirus of tomato has emerged as a significant problem (Farooq and Akanda, 2007a, 2007b).During the 2010-2011 cropping seasons of tomato, epidemics of bud necrosis disease.

Insects may spread plant diseases in the following ways: By feeding, laying eggs or boring into plants, they create an entrance point for a disease that is not actually transported by them. They carry and disseminate the causative agents of the disease on or in their bodies from one plant to a susceptible surface of another plant The problem with potatoes. In the U.S., people eat an average of 126 pounds of potatoes per person each year.

Crop rotation is the cornerstone of pest control in the tropics. When a single crop is planted repeatedly in the same soil, insects and diseases that attack that crop are allowed to build up to unmanageable levels, greatly reducing the farmer's harvest

Potato and sweet potato, short cycle crops with three to four months cropping cycle, are well suited to the double cropping seasons particularly in rain-fed systems and have significant advantage over grain crops which require longer time to harvest. Their short growing cycle allows for flexible planting and harvesting times and also permit Bacterial canker is a common and destructive disease, especially for greenhouse growers. Infected tomato seedlings develop white leaf spots and show wilting, often leading to plant death. More mature plants show symptoms on the leaves, fruit, and stems.

A variety of diseases and disorders affect onions and related crops in Ontario. Most of the diseases are caused by fungi or bacteria whereas disorders may be caused by adverse weather, air pollutants, soil conditions, nutritional imbalances and pest control products. Sometimes several diseases and/or disorders can be present at the same time requires approximately 14 520 plants per hectare. Management of water is very critical to avoid transplant shock. SOIL PREPARATION Bed formation Sweet potato is grown on raised beds or mounds. This provides the develop-ing roots with loose, friable soil to expand to their potential size and shape without restriction For effective solarization, moisten the soil, then cover it with a clear, plastic tarp. Leave the tarp in place for 4 to 6 weeks during the hottest part of summer. Root knot nematodes, including eggs, die when soil temperature exceeds 125°F for 30 minutes or 130°F for 5 minutes Disease Cycle Management Only scab free seed potatoes should be planted as this will help in checking the spread of the inoculum and infection to be subsequent crop. Infection of the seed tubers can be removed by 1.5hrs dip in mercuric chloride 0.1% solution or by 2h dip in 1 part formaldehyde in 240 parts of water of seed potatoes received as well as laboratory testing of any seed lots that might be at risk for the disease (Nolte 2005). Sanitation for seed handling. All trash left from previ-ous seasons, including potato tubers and vines, soil, old bags, broken boxes, etc. should be removed from seed stor-age areas, and properly discarded or burned

Furthermore, the prevalence and incidence of sweet potato viral diseases is high in southern parts of the country. A sweet potato yield reduction of 41-92.6 % has been reported so far due to this disease. Management practices like, cultural, resistant/tolerant varieties, insecticides (to control insect vectors To diagnose plant diseases effectively, it is necessary to understand the biology of the microorganisms that cause them: fungi, bacteria, and viruses. Fungi About 85% of plant diseases are caused by fungi: multi-celled microorganisms that may be seen without a microscope during certain stages of their life cycles. Fung diseases of pepper, tomatoes, potatoes, and other plants. In certain situations, the nematode has been responsible for breaking disease resistance to Fusarium wilt.

CHAPTER 9: POSTHARVEST INTEGRATED PEST MANAGEMENT Page 9.1 . POSTHARVEST INTEGRATED PEST MANAGEMENT . Many of the practices described so far in Part I are valuable because they help reduce pest problems during postharvest handling, storage and marketing. The first line of defense against insects and disease is good management during production management tasks such as breeding soundness exams on rams or bucks, tailoring a vaccination program to the producer's farm, purchasing supplies and vaccines from the vet, and using their services for other animals such as household pets are just a few examples. Additionally, producers can work together to obtain services from a veterinarian production of cereals, vegetables & cash crops as well as their marketing for raising the income.

What causes plant disease? •Infectious plant diseases are caused by living organisms that attack and obtain their nutrition from the plant they infect. The parasitic organism that causes a disease is a pathogen. Numerous fungi, bacteria, viruses, and nematodes are pathogens of corn and soybean in Iowa The common black and yellow-striped potato bug, a very familiar insect, is the most serious pest of potatoes. Both the adult, or beetle, and the black-spotted, red larva feed on potato leaves. Their damage can greatly reduce yield and even kill plants. Figure 3. Colorado potato beetle has alternating black and white stripes on its wing covers The International Potato Center (CIP) was founded in 1971 as a research-for-development organization with a focus on potato, sweetpotato and andean roots and tubers.
