Ditylenchus dipsaci is a plant pathogenic nematode that primarily infects onion and garlic. [2] It is commonly known as the stem nematode, the stem and bulb eelworm, or onion bloat (in the United Kingdom). [3] [4] Symptoms of infection include stunted growth, discoloration of bulbs, and swollen stems.
The larvae damage bulbs of onions, garlic, chives, shallots, leeks, and flowering plants. The first generation of larvae is the most harmful because it extends over a long period owing to the females' longevity and occurs when the host plants are small. Seedlings of onion and leek can be severely affected as can thinned-out onions and shallots. [3]
slugs, aphids, carrot fly, cabbage worms [4] Can be used like conventional chives: beans, peas, parsley: This is a wild cousin of onions and garlic Wild mustard: Brassicaceae: Grape vine, radish, non-mustard brassica, including cabbage, cauliflower, broccoli: Ladybugs: Traps various brassica pests, including aphids: Seeds and leaves are edible ...
Agriculture exploits this finding, and the inundative release of EPNs can effectively control populations of soil insect pests in citrus, cranberries, turfgrass, and tree fruit (Lewis et al. 1998). If entomopathogenic nematodes suppress the population of insect root herbivores, they indirectly benefit plants by freeing them from grazing pressure.
The onion thrips is thought to have originated in the Mediterranean region but is now found on all continents except Antarctica. [3] It infests a wide range of host plants that include onion, leek and garlic, brassicaceous plants such as cabbage, cauliflower and broccoli, asparagus, sugarbeet, melon, pumpkin, marrow and cucumber, strawberry, potato, tobacco, cotton and many fruiting and ...
Are there risks to eating edible worms and insects? As with any food, there’s always risk involved. Like with animal livestock, insects can harbor disease-causing pathogens, including E. coli ...
Thyme, nasturtiums, and onion showed good resistance to cabbage worm, weevil and cabbage looper. [28] Broccoli: Brassica oleracea: Lettuce: Beets, dill, onions, [6] tomato, [31] turnip, [32] clover [31] Broccoli as a main crop intercropped with lettuce was shown to be more profitable than either crop alone. Turnip acts as a trap crop. [32]
Control is by crop rotation (at least 3 years between successive onion crops), use of healthy bulbs for planting (heat treatment has been used to eliminate the pathogen from bulbs), fungicide treatment of the bulbs for planting, and fungicide sprays of the foliage if downy mildew infection is nevertheless observed.
