I-Chlorpyrifos iyisibulala-zinambuzane se-organophosphorus esine-spectrum esibanzi esinobuthi obuphansi uma kuqhathaniswa. Ingavikela izitha zemvelo futhi ivimbele futhi ilawule izinambuzane ezingaphansi komhlaba. Ihlala izinsuku ezingaphezu kwezingama-30. Ngakho-ke kungakanani okwaziyo mayelana nemigomo kanye nomthamo we-chlorpyrifos? Ake sibheke ngezansi. Thola.
Izinhloso zokulawula i-Chlorpyrifos nomthamo.
1. Ukuze ulawule amarola amaqabunga elayisi, ama-rice thrips, ama-rice gall midges, i-rice planthoppers namahlamvu erayisi, fafaza u-60-120 ml ka-40.7% EC ngamanzi ehektare ngalinye.
2. Izinambuzane zikakolweni: Ukuze ulawule amaqabunga kakolweni, sebenzisa izibulala-zinambuzane ezigabeni zokuqala zesifo; ukulawula ama-aphid, sebenzisa izibulala-zinambuzane ngaphambi noma ngemva kokuqhakaza; ukulawula izikelemu, fafaza izibulala-zinambuzane lapho ziseyizibungu. Ngokuvamile, u-60-80ml we-40% EC uxutshwa nama-30-45kg wamanzi ngehektare ngayinye; ukulawula izikelemu kanye nama-aphid, 50-75ml ka-40.7% EC isetshenziswa ihektare ngalinye bese kuthi u-40-50kg wamanzi ufuthwe.
3. I-corn borer: Ngesikhathi sesiteji sommbila, sebenzisa u-80-100g wezinhlamvu ezingu-15% ukuze usakaze emaqabunga enhliziyo.
4. Izinambuzane zikakotini: Lapho ulawula izintwala zikakotini, izimbungulu ze-lygus, ama-thrips, ama-weevil, nezinambuzane ezakha amabhuloho, fafaza izibulala-zinambuzane lapho inani lezinambuzane landa ngokushesha; lapho ulawula izikelemu zikakotini nezikelemu ezibomvana, fafaza izibulala-zinambuzane ngesikhathi sokuchanyuselwa kwamaqanda ezibungwini Fafaza ngaphambi kokuba ubhoboze amahlumela. Ngokuvamile, fafaza u-100-150ml we-concentrate engu-40% emulsifiable kanye no-45-60kg wamanzi ihektare ngalinye.
5. Izimpande zezimpethu zamaliki kanye negalikhi: Ezigabeni zokuqala zokuvela kwempethu, u-400-500ml ka-40% EC ngehektare kufanele uniselwe ngamanzi okunisela.
6. Ukulawula izinambuzane zikakotini, sebenzisa u-50 ml ka-40.7% we-chlorpyrifos EC ngehektare ngalinye kanye no-40 kg wesifutho samanzi. Kuma-spider mite kakotini, sebenzisa u-70-100 ml ka-40.7% we-Lesbourne EC ngehektare futhi ufafaze ngamanzi angama-40 kg. Sesha Umbuthano Wokulima Imifino ku-WeChat ukuze unake. Ngezikelemu zikakotini nezikelemu ezipinki, sebenzisa u-100--169 ml ihektare ngalinye bese ufutha ngamanzi.
7. Ngezinambuzane ezingaphansi komhlaba: njengama-cutworms, ama-grubs, ama-wireworms, njll., nisela isisekelo sezitshalo izikhathi ezingu-800-1000 ze-40% EC ihektare ngalinye.
8. Ukulawula izinambuzane zezihlahla zezithelo, abavukuzi bamaqabunga e-citrus kanye nezibungu zesicabucabu kufanele zifuthwe izikhathi ezingu-1000-2000 ze-40.7% EC. Sebenzisa isifutho se-liquid izikhathi ezingama-400-500 ukwelapha izikelemu zenhliziyo. Lesi silinganiso singasetshenziswa futhi ukulawula izibungu zesicabucabu se-hawthorn kanye nezibungu zesicabucabu sama-apula.
9. Izinambuzane ezidla imifino: njengezibungu zeklabishi, amabhu e-diamondback, ama-aphid, amathrips, izimpukane, njll. zingafuthwa ngo-100-150ml ka-40% EC oxutshwe namanzi angama-30-60kg.
10. Ukulawula izinambuzane zikamoba, fafaza u-20 ml ka-40.7% EC ngamanzi ehektheni ngalinye ukuze ulawule izintwala zoboya bomoba.
11. Ukulawula izinambuzane zemifino, sebenzisa u-100-150 ml ka-40.7% we-chlorpyrifos EC ngehektare elifuthwe ngamanzi.
12. Ukulawula izinambuzane zesoya, fafaza u-40.7% EC 75--100 ml ngamanzi ehektare ngalinye.
13. Ukulawula izinambuzane ezihlanzekile, sebenzisa isifutho se-100-200 mg/kg komiyane abadala. Umthamo womuthi wezibungu ngu-15-20 mg/kg emanzini. Kumaphela, sebenzisa ama-200 mg/kg. Emazeze, sebenzisa ama-400 mg/kg. Sebenzisa u-100--400 mg/kg ukuze ugcobe noma ugeze imikhaza yezinkomo ezincane namazeze ebusweni bemfuyo.
14. Ukuze ulawule izinambuzane zesihlahla setiye, sebenzisa isifutho esiwuketshezi esinesilinganiso esisebenzayo izikhathi ezingama-300-400 kuma-geometrids wetiye, amabhu etiye, amacimbi etiye, amabhu aluhlaza, ama-tea gall mites, ama-tea orange gall mites, nezimbuzane ezinentshebe emfishane. .
Kunezindlela ezintathu eziyinhloko zokulawula izinambuzane nge-chlorpyrifos:
1. Futha. Nciphisa u-48% we-chlorpyrifos EC ngamanzi bese ufutha.
1. Sebenzisa izikhathi ezingu-800-1000 zoketshezi ukuze ulawule izibungu ze-American leafminer ezinamachashaza, i-tomato spotted flyminer, i-pea leafminer, i-leafminer yeklabishi nezinye izibungu.
2. Sebenzisa uketshezi oluphindwe izikhathi eziyi-1000 ukuze ulawule isibungu seklabishi, izibungu ze-Spodoptera litura, izibungu zebhu le-lamp, i-melon borer nezinye izibungu nemifino yasemanzini.
3. Sebenzisa izikhathi eziyi-1500 isisombululo ukuze uvimbele futhi ulawule izibungu eziphuphumayo zomvukuzi wamaqabunga aluhlaza kanye nezibungu ze-yellow spot borer.
2. Ukuchelela ngezimpande: Dilute 48% chlorpyrifos EC ngamanzi bese unisela izimpande.
1. Ngesikhathi sokuzala kwezimpethu ze-leek, sebenzisa ukukhanya okuwuketshezi okuphindwe izikhathi ezingu-2000 ukuze ulawule izimpethu ze-leek, futhi usebenzise amalitha angu-500 omuthi owuketshezi ihektare ngalinye.
2. Uma unisela ugalikhi ngamanzi okuqala noma esibili, sebenzisa u-250-375 ml we-EC ngehektare futhi usebenzise isibulala-zinambuzane emanzini ukuvimbela izimpethu.
