Txawm hais tias kev lag luam rov hais dua rau cov neeg siv khoom, tsim cov ntawv sau cov organic tsis yog ib txwm raug rau txhua yam-natural tshuaj. Txhawm rau npog cov ntsiab lus tseem ceeb ntawm kev ua tiav kev ua liaj ua teb, Tebchaws Asmeskas Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb (USDA), los ntawm lawv Lub Tebchaws Organic Program (NOP), tuav cov npe ntawm cov tshuaj hluavtaws uas lawv tso cai rau cov neeg ua liaj ua teb siv rau kev ua liaj ua teb organic.
Top 10 USDA Organic Farming Chemicals
Raws li NOP cov kev ntsuam xyuas, cov tshuaj hluavtaws raug txiav txim siab siv thaum "nws tsis tuaj yeem tsim los ntawm lub ntuj tsim thiab tsis muaj cov organic hloov," thiab cov khoom tseem ceeb rau kev tuav cov khoom organic (saib Subpart G, § 205 Ib.600, yam khoom (b)(2) thiab (b)(6) ntawm US Electronic Code of Federal Regulations list). Tsis tas li ntawd, kom tau txais kev pom zoo, cov tshuaj yuav tsum tsis muaj kev paub txog kev cuam tshuam rau ib puag ncig lossis kev noj qab haus huv ntawm cov neeg siv khoom.
Lub Tebchaws Organic Standards Board (NOSB) pom zoo rau NOP yam uas yuav tsum tau ntxiv lossis tshem tawm ntawm cov npe tshuaj hauv tebchaws tau pom zoo rau kev ua liaj ua teb organic. Cov npe nram qab no ntawm kaum cov khoom siv hluavtaws (tso npe nyob rau hauv Electronic Code of Federal Regulations, Subpart G, section 205.601) muaj rau cov neeg ua liaj ua teb organic rau qhov tseem ceeb xws li tshuaj tua kab, tshuaj tua kab mob, tswj cov nroj tsuag thiab lwm yam overgrowth, thiab tswj cov av zoo thaum Tsis muaj cov khoom siv organic.

- Nyob rau hauv av irrigation system tu tshuab
Cov tshuaj chlorine tsuas yog siv rau hauv cov khoom uas txwv cov tshuaj chlorine seem hauv cov dej uas nkag mus rau cov nroj tsuag, lossis hauv cov dej hauv cov kav dej uas nkag mus rau hauv av.
3. Tooj Sulfate
Cov neeg ua liaj ua teb tuaj yeem siv tooj liab sulfate rau:
- Suppress algae loj hlob hauv dej ua liaj ua teb
- Control tadpole cw hauv dej ua liaj ua teb
- Tau tua kab, kab mob, fungi, nroj tsuag, slugs
Tus neeg ua liaj ua teb organic tsis raug tso cai siv ntau dua ib zaug txhua 24 lub hlis, thiab nyob rau hauv ib qho nyiaj uas tsis nce qib tooj liab hauv cov av saum toj ib qho kev pom zoo hauv lub sijhawm pom zoo.
4. Peracetic Acid
Peracetic acid yog siv:
- To disinfect farm machinery
- Tau tshuaj tua kab mob rau cov noob thiab cov nroj tsuag pib
- Tau tswj cov kab mob fungal lossis kab mob blight
- Post-harvest zaub mov processing
Nws tseem tso cai rau cov khoom siv hydrogen peroxide siv los ua tshuaj tua kab thiab tshuaj tua kab.
5. Soap-based Herbicides
Zoo li tshuaj tua kab yog siv los ua tshuaj tua kab thiab tswj cov nroj tsuag thiab kev loj hlob ntawm cov nroj tsuag:

- Building perimeters
6. Ammonium Carbonate
Ammonium carbonate yog siv los dai cov ntxiab kom yoov thiab lwm yam kab. Cov tshuaj tsis tuaj yeem tso cai rau cov qoob loo lossis av.
7. Boric Acid yog qhov zoo tshaj plaws rau kev noj qab haus huv
Boric acid tuaj yeem siv rau kev tswj kab tsuag hauv tsev. Nws kuj tseem siv rau hauv cov kua txiv hmab txiv ntoo ua lub hauv paus rau lub caij boron los txhawb kev loj hlob ntawm cov nroj tsuag noj qab haus huv.
8. Sodium Carbonate Peroxyhydrate
Hauv kev ua liaj ua teb organic, sodium carbonate peroxyhydrate yog siv los ua tshuaj tua kab mob, tshuaj tua kab mob, ntxuav cov kav dej, thiab ua cov tshuaj tua kab mob thiab tshuaj tua kab mob.
9. Sulfur Tshuaj
Sulfur tshuaj xws li elemental sulfur thiab txiv qaub sulfur raug tso cai:
