Poukisa sèvi ak ensèk-prèv may?

Objektif prensipal may ensèk-prèv se kenbe ensèk tankou papiyon chou blan epi skarabe pis koupe rekòt. Kreye yon baryè fizik kapab efikas ak yon altènatif pou itilize pestisid. 

May la sanble yon ti kras tankou rido nèt men se te fè nan politèn klè. Gwosè may yo siyifikativman pi ouvè pase polaire ortikol sa vle di li bay ti chalè siplemantè. Sepandan, li bay bon pwoteksyon van, lapli ak lagrèl.

Avantaj

Pwoteksyon kont ensèk yo 

Itilize kòm yon baryè fizik, may prèv ensèk bay pwoteksyon kont ensèk manje plant souvan san ogmantasyon siyifikatif nan tanperati (selon gwosè may) men ak bon pwoteksyon kont van ak lagrèl. Yo menm tou yo entèsepte gwo lapli diminye domaj ke gwo lapli ka fè nan estrikti tè a, kabann grenn ak plant. Eklatman tè ki ka kontamine rekòt fèy yo tou redwi.

Many problems including root feeding insects such as kawòt vole epi vole rasin chou are better managed by insect proof mesh than pesticides and the extra shelter leads to better plants and heavier crops.

Stretching mesh, even by placing over hoops, can widen the gaps and reduce efficacy. Check manufacturer’s instructions. The edges of the mesh are best buried under at least 5cms of soil.

Plant yo pa ta dwe restrenn pandan y ap grandi anba kouvèti may ak kanson yo ta dwe enkli lè kouvri pou pèmèt plant yo grandi.

Malgre ke horticultural fleece can exclude invertebrates very effectively, it is much less durable and can be easily damaged when removed for weed control. Fleece can also raise temperatures and humidity to levels that might be undesirable.

Wotasyon rekòt should be practised, as some invertebrates can get through the mesh and might persist until the following year, ready to multiply when the same crop is planted and the mesh replaced.

Dezavantaj

Limite kaptire nan chalè

Polaire should be used where crops need to be provided with extra warmth or frost protection.

Ankouraje maladi ak bal

Raised humidity levels and subsequent soft, lush growth produced when growing under insect proof mesh may encourage diseases such as Botrytis epi kanni. Bales epi Molisk ka ankouraje pa imidite ki pi wo anba may.

Limite aksè nan move zèb

Malerezman, anjeneral li nesesè dekouvwi plant chak de a twa semèn pou raje, raje ak tou mens plant simen. Sa a riske antre nan ensèk nuizib ki yon fwa andedan may la gen anpil chans pou miltipliye.

Ze ki tap mete nan may la

Ensèk yo ka pafwa ponn ze nan may la si may la manyen feyaj rekòt la. Asire ke may la pa manyen plant yo diminye chans pou sa rive. 

Pwoblèm polinizasyon

Rekòt polinize ensèk yo tankou frèz epi kouriz yo pa apwopriye pou grandi anba may ensèk yo pandan peryòd flè yo.

Filet ak bèt sovaj

Animaux sovaj yo ka an danje nan yon filè jaden mal bati ak jere. Trè byen may, tankou ensèk-prèv may oswa polaire ortikol, se youn nan opsyon ki pi an sekirite, men li esansyèl pou an sekirite bor yo nan may la lè yo antere anba tè a oswa ancrage nan yon tablo nivo tè mwatye koule nan tè a. Zwazo an patikilye ka vin mele nan filè ki lach ki ka lakòz lanmò yo oswa blesi. 

Dirab

Insect proof mesh may last five to ten years but unfortunately cannot be easily recycled. However, local recycling facilities should be checked. Insect netting made from biodegradable plant starch is now available from Andermatt, bay jardinage yon opsyon ekolojik-zanmi. 

Chwa pwodwi

Insect-proof mesh is offered in pre-cut sizes, a variety of widths and any length can be ordered ‘off the roll’. The larger the sheet and the closer it is to manufactured sizes the less it costs per square metre.

May yo vann tou nan diferan gwosè may. Plis pi piti may la pi piti ensèk la eskli, men se pi gwo pri a ak tou potansyèl ogmantasyon nan tanperati (pi rafine materyèl prèv ensèk ka mennen nan yon chofe enpòtan pou rekòt ki kouvri yo) ak imidite anba. Nan lòt men an, pi rafine may yo gen tandans pi lejè ak pi fasil yo sèvi ak san yo pa sipòte sèrkl.

Estanda may: 1.3-1.4mm. Bon pou ensèk tankou mouch rasin chou, vole zonyon, grenn pwa vole epi carrot fly, as well as moth and butterfly pests.  Birds and mammals can also be excluded. Although theoretically capable of penetrating mesh, mammals and larger birds seldom do, so there is rarely any need to add further protection such as bird netting. However, this size is unreliable in excluding small insects such as afid, skarabe pis, allium fèy miner epi papiyon pwaro.

Amann may: 0.8mm. Good for very small insects such as flea beetles, cabbage whitefly, moth and butterflies, leaf miners (including allium leaf miner), mouch vèt, blackfly, osi byen ke vole rasin chou, vole zonyon, vole grenn pwa ak vole kawòt. Zwazo ak mamifè yo tou eskli.

May ultrafin: 0.3-0.6mm. Gwosè sa a bay bon pwoteksyon kont trips, insect pis ak lòt envètebre ki piti anpil. Zwazo ak ensèk nuizib mamifè yo tou eskli.

Filet papiyon: Filè amann ak yon may 4-7mm bay bon pwoteksyon kont papiyon blan osi lontan ke feyaj la pa manyen nèt la, ak nan kou zwazo ak mamifè.
