Kev sib xyaw ntawm cov tshuaj tua kab thiab tshuaj tua kab yog qhov teeb meem nyuaj dua. Tsis yog txhua yam tshuaj tua kab tuaj yeem sib xyaw. Cov ntsiab lus hauv qab no yuav tsum tau them siab rau thaum sib xyaw:
1. Cov pH yog ib qho tseem ceeb cuam tshuam rau kev ua tau zoo ntawm txhua feem. Nyob rau hauv Alkaline cov xwm txheej, carbamates, pyrethroid cov tshuaj tua kab, theram, dithiocarbamic fungicy lossis ntau yam tshuaj hloov pauv, yog qhov rhuav tshem cov qauv txheej txheem qub. Nyob rau hauv acidic tej yam kev mob, 2,4-d sodium ntsev, 2-methyl-4 chloride ntsev ntsev, thiab lwm yam yuav decomais, li txo cov kev ua tau zoo ntawm cov tshuaj.
2. Organosulfur thiab organophosphorus tshuaj tua kab mob tsis tuaj yeem sib xyaw nrog cov tshuaj tua kab, vim tias lawv tau npaj nrog tooj liab ions, thiab poob haujlwm.
3. Microbial tshuaj tua kab thiab cov txheej txheem organophosphorus tsis tuaj yeem sib xyaw nrog cov fungicides.
4. Rau kev siv sib xyaw ntawm emulsifued concentrates lossis wettable hmoov, tsis muaj delamination, roj slick, redimentation, thiab lwm yam yuav tsum muaj.
5. Nws yog qhov tsim nyog kom tsis txhob phytotoxicity ntawm cov sib tov. Cov tshuaj hloov pauv ntawm cov khoom xyaw nquag hauv cov khoom sib xyaw ua ke yuav ua rau phytotoxicity. Piv txwv li, kev sib xyaw ntawm cov txiv qaub sulfur sib tov thiab Bordeaux sib tov tuaj yeem tsim cov khoom zoo li cov neeg tooj liab ES; Nyom amine, etc. tsis tuaj yeem sib xyaw nrog organophosphorus thiab carbamate cov tshuaj tua kab.
6. Cov tshuaj tua kab, fungicides thiab cov tshuaj tua kab yog tov nrog tsawg dua ntau yam.
7. Muaj ntau ntau yam ntawm cov tshuaj lom neeg fungicide, feem ntau yog suav nrog cov noob hnav khaub ncaws ob chav, hlauasxyl mumpcozesb, polysulfed ntawm cov pos hniav, thiab tuijune.
8. Muaj ob peb ntau yam tshuaj ntawm cov nroj tsuag kev loj hlob regulators. Xws li kev siv gibberellin thiab chlormequatat, sib xyaw ntawm gibberellin thiab naphthalene acetic acid thiab li ntawd.
