Uyisebenzisa njani iPesticide ngokuchanekileyo?

Ukusetyenziswa kwezibulali zinambuzane ukuthintela nokulawula izifo, izitshabalalisi, ukhula, neempuku ngumlinganiselo obalulekileyo wokufumana isivuno esikhulu sezolimo.Ukuba isetyenziswe ngokungafanelekanga, inokungcolisa indalo esingqongileyo kunye nemveliso yezolimo neyemfuyo, ibangele ityhefu okanye ukufa ebantwini nakwimfuyo.

Ulwahlulo lwezitshabalalisi:

Ngokutsho kovavanyo olubanzi lwetyhefu (ityhefu yomlomo ebukhali, ityhefu yedermal, ityhefu engapheliyo, njl.njl.) yezibulali-zinambuzane ezisetyenziswa ngokuqhelekileyo (izinto eziphathekayo) kwimveliso yezolimo, zohlulwe zibe ziindidi ezintathu: ubutyhefu obuphezulu, ubuthi obuphakathi, kunye nobutyhefu obuphantsi.

1. I-pesticides enetyhefu ephezulu ibandakanya i-3911, i-Suhua 203, i-1605, i-Methyl 1605, i-1059, i-Fenfencarb, i-Monocrofos, i-Phosphamide, i-Methamidophos, i-Isopropaphos, i-Trithion, i-omethoate, i-401, njl.

2. Izitshabalalisi ezinetyhefu ephakathi ziquka ifenitrothion, dimethoate, Daofengsan, ethion, imidophos, picophos, hexachlorocyclohexane, homopropyl hexachlorocyclohexane, toxaphene, chlordane, DDT, kunye nechloramphenicol, njl.

3. Izilwanyana ezinobuthi obuphantsi zibandakanya i-trichlorfon, i-marathon, i-acephate, i-phoxim, i-diclofenac, i-carbendazim, i-tobuzin, i-chloramphenicol, i-diazepam, i-chlorpyrifos, i-chlorpyrifos, i-glyphosate, njl.

Izitshabalalisi ezinetyhefu ephezulu zinokubangela ityhefu okanye ukufa ukuba zibekwe kwindawo encinci kakhulu.Nangona ityhefu yezitshabalalisi ezinetyhefu ephakathi kunye nephantsi isezantsi noko, ukuba sesichengeni rhoqo kunye nokuhlangulwa kwangethuba nako kunokukhokelela ekufeni.Ngoko ke, kuyimfuneko ukunikela ingqalelo kukhuseleko xa usebenzisa i-pesticides.

Ubungakanani bosetyenziso:

Zonke iindidi ezimisele "imigangatho yokusetyenziswa kokhuseleko lwesitshabalalisi" ziya kuthobela iimfuno "zemigangatho".Kwiintlobo ngeentlobo ezingekamiselwa “imigangatho”, oku kulandelayo kuya kuphunyezwa:

1. Izitshabalalisi ezinetyhefu ephezulu azivumelekanga ukuba zisetyenziswe kwizityalo ezifana nemifuno, iti, imithi yeziqhamo, kunye namayeza esintu aseTshayina, kwaye ayivumelekanga ukuba isetyenziswe ekuthinteleni nasekulawuleni izitshabalalisi zempilo kunye nezifo zolusu lwabantu kunye nezilwanyana.Ngaphandle kwemichiza ye-rodenticides, ayivumelekanga ukuba isetyenziswe kwiimpuku ezinetyhefu.

2. Izibulali-zinambuzane ezishiyekileyo ezifana ne-hexachlorocyclohexane, i-DDT, ne-chlordane azivumelekanga ukuba zisetyenziswe kwizityalo ezifana nemithi yeziqhamo, imifuno, imithi yeti, iyeza lesintu laseTshayina, icuba, ikofu, ipepile kunye ne-citronella.I-Chlordane ivumeleke kuphela ukunxitywa kwembewu kunye nokulawula izinambuzane eziphantsi komhlaba.

3. I-Chloramid ingasetyenziselwa ukulawula isigcawu somqhaphu, i-rice borer, kunye nezinye izitshabalalisi.Ngokweziphumo zophando kwityhefu yechlorpyrifos, ukusetyenziswa kwayo kufuneka kulawulwe.Ngethuba lonke ixesha lokukhula kwerayisi, ivumelekile ukuba isetyenziswe kanye kuphela.Sebenzisa i-2 taels yamanzi angama-25% ngehektare nganye, ubuncinane beentsuku ezingama-40 ukusuka kwixesha lokuvuna.Sebenzisa iithali ezi-4 zama-25% amanzi ngehektare nganye, ubuncinane iintsuku ezingama-70 ukususela kwixesha lokuvuna.

4. Akuvumelekanga ukusebenzisa izibulali-zinambuzane ukutyhefa iintlanzi, i-shrimp, amasele, neentaka nezilwanyana eziluncedo.
