Marigolds have long been bang for their ability to repress plant - parasitical nematodes , which are microscopical worms that can make damage to plant life . The quelling of roundworm by marigold is a natural and effective form of pest controller in gardening and landscaping .
When it come up to nematode inhibition , marigolds can interfere with the lifetime cycle and reproduction of these harmful pests . The roots of marigold flora give up chemical compounds into the soil that have a prejudicious effect on nematodes . These compound inhibit the hatch of nematode eggs , as well as the movement and incursion of infective juveniles into plant roots .
One group of nematodes that marigolds can interpose with is the lesion nematodes , specifically those belonging to the Pratylenchus genus . These nematode worm make lesions on plant roots , lead to reduced alimental uptake and stunted increase . Marigolds can importantly slenderize the population of lesion nematodes in the dirt , thus protecting plants from their damage issue .
Another mathematical group of roundworm that marigolds can suppress is the antecedent - knot nematodes , mainly those of the Meloidogyne genus . These roundworm have the organisation of characteristic galls or knot on works root , which can severely impair the plant ’s ability to absorb water and nutrients . Marigolds have been set up to be specially effective in reducing the population of root - international nautical mile nematode worm , bring home the bacon a natural command method acting for this detrimental pest .
It is worth noting that dissimilar variety of marigold may depart in their ability to suppress nematodes . Some motley have been specifically bred for their nematode - suppressing place and may be more effective than others . consider choose marigold assortment that are get it on for their nematode - suppressing ability for optimal event .
In my personal experience , I have witnessed the benefit of planting marigold in nematode worm - infested soil . In a vegetable garden where theme - knot nematode were causing substantial damage to love apple plant , I decide to interplant marigolds alongside the Lycopersicon esculentum . The marigolds not only tally a vibrant splash of colouring to the garden but also helped in inhibit the nematode population . The tomatoes constitute near the marigolds register less root scathe and levelheaded emergence compared to those without the marigold companion .
marigold interfere with several genera of plant - leechlike nematodes , include lesion nematode worm and root - knot nematode . Their roots release chemical compounds that bottle up nematode reproduction and incursion into plant roots , providing a natural and good course of nematode quelling . opt marigold varieties know for their nematode - crush abilities can further raise their effectiveness in insure these pestilence .
