The main symptoms of Ditylenchus destructor, common to potatoes and its other hosts, are the rotting and discoloration of subterranean plant tissue. In potatoes, early infection can be detected by small white spots underneath the potato's skin. As the disease progresses, these spots become larger and darker with a spongy or hollow appearance. [7]
The pronotum and wing covers are covered in dense, short greyish hairs. The larva is known as a wireworm and lives in the soil. It is yellow, slender, stiff and leathery, and grows to a length of about 20 mm (0.8 in). The centre of the mandible has a small tooth for gnawing. [3]
To avoid this, the tuber used as seed has to be produced under conditions of strict disease control, which increases the cost of propagation material and thus limits its availability or increases farmers' production costs. Micropropagation offers an economical solution to the problem of the presence of pathogens in seed potatoes. The starting ...
Place potatoes in the water, and let them soak for 15 minutes to allow dirt and grime to loosen. Using a vegetable brush, thoroughly scrub the potatoes to remove dirt from the skins.
Click beetle larvae, called wireworms, are usually saprophagous, living on dead organisms, but some species are serious agricultural pests, and others are active predators of other insect larvae. Some elaterid species are bioluminescent in both larval and adult form, such as those of the genus Pyrophorus .
You can put them on a baking sheet and leave them out to “callous over” for 24 hours to develop a harder skin which may help prevent the potato from rotting if the soil is very wet, says ...
Monocrepidius falli, the southern potato wireworm, is a species of click beetle in the family Elateridae. References This page was last edited on 12 October ...
If possible, ask for seed potatoes grown on fields which were declared free of the potato cyst nematode. Pesticides can be used, but they will not get a field free of nematodes. They will increase yields and are only profitable at high population densities, when the financial profit of the extra yield will surpass the cost of the pesticide ...
