6 TAGETES – 6.33 - MARIGOLDS KILLS HARMFUL NEMATODES

                    

They Produce Chemicals Effective Against Harmful Nematodes

Marigolds are famously excellent as a companion plant. One way in which marigolds are said help their neighbours is by killing nematodes that can cause problems for crops.

What Are Nematodes? 

Nematodes are tiny organisms, roundworms, which constitute the phylum Nematoda. The word nematode comes from the Modern Latin ‘nemat’ (thread) (from Greek ‘nema’) and ‘odes’ (like, of the nature of). There are a huge number of different species of these small, thread-like creatures.

Some nematodes cause problems for plants and people. But others are beneficial – involved in some important jobs in the soil and around your garden.

Can Planting Marigolds Really Help With Nematode Problems?

There is a lot of confusion surrounding this issue. The subject is not as clear cut as some gardeners believe. Marigolds do produce compounds in their roots that are nematicides.

But it is important to understand that there are a huge range of different nematodes that can become a problem, and home gardeners will usually be unable to determine which ones they have in their soil.

When certain French marigolds are infested with certain nematodes, they kill them off in that spot and reduce their numbers. This can bring harmful nematode populations down.

 Marigolds may also excrete a chemical which can repel nematodes in the surrounding area (though scientists disagree over whether this is the case).

Companion planting with marigolds may help some nearby plants, though the science is currently inconclusive.

Planting marigolds in each, exact location in your vegetable beds before the vegetables can, however, definitely reduce certain nematodes there and make it less likely that crops immediately following them will be struck.

Which French Marigolds are Most Effective?

Some French marigold cultivars produce higher levels of toxin and are therefore more effective in reducing the number of pest nematodes in soil. ‘Tangerine’, ‘Petite Gold’, ‘Petite Harmony’, ‘Goldie’, and ‘Nemagold’ are said to be particularly effective. They work most effectively when planted closely spaced in a solid block.

 

Marigolds produce these secretions around 3-4 months after sowing, so must be grown for a length of time to effectively reduce the nematode populations.

Including them in a crop rotation could therefore be more effective than simply placing a few between your other plants. Leaving roots in situ at the end of the growing season can help to increase the efficacious effect.

Growing marigolds can help control a nematode population, such as root rot nematodes.

However, it is important to realise that it will help control them, not get rid of them altogether. Marigolds may help reduce the harmful nematode population, at least short term.

But if you have a severe problem, you may also have to consider choosing and growing resistant varietals, or implementing othes-

 Hutoa Kemikali Zinazofaa Dhidi Ya Nematodi Wadhuru

Marigolds ni maarufu kama mmea mwenza. Njia moja ambayo marigold inasemekana kusaidia majirani zao ni kwa kuua nematodes ambayo inaweza kusababisha matatizo kwa mazao.

Nematodes ni nini?

Nematodes ni viumbe vidogo vidogo, minyoo ya mviringo, ambayo hujumuisha phylum Nematoda. Neno nematode linatokana na neno la Kilatini la Kisasa ‘nemat’ (nyuzi) (kutoka kwa Kigiriki ‘nema’) na ‘odes’ (kama, ya asili ya). Kuna idadi kubwa ya spishi tofauti za viumbe hawa wadogo, kama nyuzi.

Baadhi ya nematode husababisha matatizo kwa mimea na watu. Lakini zingine ni za manufaa - zinahusika katika baadhi ya kazi muhimu katika udongo na karibu na bustani yako.

Je, Kupanda Marigolds Kweli Kutasaidia na Matatizo ya Nematode?

Kuna mkanganyiko mwingi unaozunguka suala hili. Somo sio wazi kama waamini wengine wa bustani. Marigolds huzalisha misombo katika mizizi yao ambayo ni nematicides.

Lakini ni muhimu kuelewa kuwa kuna anuwai kubwa ya nematodi tofauti ambazo zinaweza kuwa shida, na watunza bustani kawaida hawataweza kuamua ni zipi wanazo kwenye udongo wao.

Wakati marigolds fulani wa Kifaransa wamejaa nematodes fulani, huwaua mahali hapo na kupunguza idadi yao. Hii inaweza kupunguza idadi ya nematode hatari.

 

Marigolds pia inaweza kutoa kemikali ambayo inaweza kufukuza nematodi katika eneo jirani (ingawa wanasayansi hawakubaliani kama hii ndio kesi au la).

Kupanda pamoja na marigold kunaweza kusaidia mimea iliyo karibu, ingawa sayansi kwa sasa haina mashiko.

Kupanda marigolds katika eneo fulani, mahali halisi kwenye vitanda vyako vya mboga kabla ya mboga inaweza, hata hivyo, kwa hakika kupunguza nematodi fulani huko na kufanya uwezekano mdogo kwamba mazao yanayofuata yatapigwa.

Je, ni Marigold gani ya Kifaransa ambayo yanafaa zaidi?

Baadhi ya mimea ya Kifaransa ya marigold hutoa viwango vya juu vya sumu na kwa hiyo ni bora zaidi katika kupunguza idadi ya nematodes wadudu katika udongo. 'Tangerine', 'Petite Gold', 'Petite Harmony', 'Goldie', na 'Nemagold' inasemekana kuwa na ufanisi hasa. Wanafanya kazi kwa ufanisi zaidi wakati wa kupanda kwa karibu nafasi katika block imara.

 

Marigolds hutoa majimaji haya karibu miezi 3-4 baada ya kupanda, kwa hivyo lazima ikuzwe kwa muda mrefu ili kupunguza idadi ya nematode.

Kwa hivyo, kuzijumuisha katika mzunguko wa mazao kunaweza kuwa na ufanisi zaidi kuliko kuweka chache kati ya mimea yako mingine. Kuacha mizizi katika situ mwishoni mwa msimu wa ukuaji inaweza kusaidia kuongeza athari ya ufanisi.

Kukua marigolds kunaweza kusaidia kudhibiti idadi ya nematode, kama vile nematode za kuoza kwa mizizi.

Ugonjwa wa nematode wa mizizi

Hata hivyo, ni muhimu kutambua kwamba itasaidia kuwadhibiti, sio kuwaondoa kabisa. Marigolds inaweza kusaidia kupunguza idadi ya nematode hatari, angalau kwa muda mfupi.

Lakini ikiwa una shida kali, unaweza pia kuzingatia kuchagua na kukuza aina sugu, au kutekeleza zingine:
