"Pesticide Resistance" yog dab tsi?Kho ntau qhov kev nkag siab tsis zoo

Tshuaj tiv thaiv kab mob: txhais tau hais tias thaum kab / kab mob tiv tauj cov tshuaj tua kab, nws yuav tsim kev tiv thaiv los ntawm cov tiam tom ntej.

Yog vim li cas rau tsim tsis kam:

A,Target kab xaiv evolution

B,Target kab / kab mob fertility yam ntxwv los tsim cov tshuaj tiv thaiv

Piv txwv li, aphids rov tsim dua kaum ob tiam hauv ib xyoos, uas yog nquag rau tshuaj tiv thaiv;hom qoob mog rusty kab mob, tus nqi ntawm spores yog loj, lub explosiveness yog muaj zog, thiab nws yog nquag mus rau yeeb tshuaj.

C,Kev siv tsis tsim nyog

-Thov siv cov tshuaj tua kab ib zaug ntxiv rau lub sijhawm ntev

-Tshaj qhov kev thov kom nce siab ntxiv

- Txau tsis sib npaug

Yuav ua li cas ncua tshuaj tua kab mob

A,Siv cov tshuaj sib tov

1, Xaiv cov tshuaj tua kab sib xyaw, xws li Organic phosphorus tshuaj tua kab thiab tshuaj tua kab Chrysanthemum.

Tshuaj tua kaburing larva theem

Tshuaj tua kab moblub sij hawm seedling

Tshuaj tua kab mobisease ntxov theem

C,Tsis txhob nce qhov kev siv concentration

Thov siv nruj me ntsis raws li daim ntawv qhia kev qhia, nce qhov concentration tsis tuaj yeem ua tiav cov txiaj ntsig zoo dua.

Qee qhov kev nkag siab tsis zoo yuav tsum tau kho:

一 、 Lub sijhawm ua haujlwm ntev, qhov zoo dua 

Cov neeg feem coob xav tias cov tshuaj tua kab, tshwj xeeb tshaj yog cov tshuaj tua kab, zoo dua lub sijhawm zoo.Qhov no yog kev nkag siab yuam kev.Cov tshuaj tua kab zoo li no yuav ua rau muaj kev tiv thaiv.Cov saum toj no, tab sis nyob rau hauv tus txheej txheem ntawm qeeb cov nyhuv, los ntawm lwm qhov chaw, ib pawg ntawm cov kab tsuag yog tsiv los ntawm lwm qhov chaw.Qhov concentration ntawm cov tshuaj residual concentration ntawm cov qoob loo yuav tsis tua kab txawv teb chaws lawm.Tom qab ntawd, cov xeeb leej xeeb ntxwv yuav sai sai tsim kev tiv thaiv.Nws kuj tseem tuaj yeem nkag siab: cov tshuaj tua kab residual induce lawv los tsim kev tiv thaiv.

二 、 Qhov ntau dua cov tshuaj tua kab concentration, cov nyhuv zoo dua

Ntawm qhov teeb meem ntawm qhov concentration ntawm cov tshuaj, ntau tus neeg ua liaj ua teb cov phooj ywg xav tias qhov ntau dua cov tshuaj tua kab ntau dua, cov txiaj ntsig zoo dua.Qhov no yog kev nkag siab tsis ncaj ncees lawm, thiab tsis hais txog qhov cuam tshuam ntawm cov tshuaj muaj peev xwm puas tsuaj ntawm qhov ntau npaum li cas ntawm cov qoob loo.Hais txog, nws kuj tsis tsim nyog.Qhov laj thawj zoo ib yam li yav dhau los, uas yog, txawm tias muaj zog npaum li cas ntawm tus neeg sawv cev tshuaj, kuj tseem muaj cov khoom tsim kev puas tsuaj nrog cov nets.Ces lawv cov xeeb leej xeeb ntxwv tau nce ceev ceevy.
