I-Chlorpyrifos sisitshabalalisi esibanzi se-organophosphorus esinetyhefu esezantsi noko. Inokukhusela iintshaba zendalo kwaye ithintele kwaye ilawule izitshabalalisi eziphantsi komhlaba. Ihlala ngaphezu kweentsuku ezingama-30. Ke ungakanani owaziyo malunga nokujoliswe kuko kunye nomthamo we-chlorpyrifos? Makhe sijonge ngezantsi. Fumanisa.
Iithagethi zolawulo lweChlorpyrifos kunye nedosi.
1. Ukulawula iirola zamagqabi erayisi, i-rice thrips, i-rice gall midges, i-rice planthoppers kunye ne-rice leafhoppers, fafaza i-60-120 ml ye-40.7% EC ngamanzi nge-acre.
2. Izitshabalalisi zengqolowa: Ukulawula amagqabi engqolowa, sebenzisa izibulali-zinambuzane kumanqanaba okuqala esifo; ukulawula iintwala, sebenzisa izibulali-zinambuzane ngaphambi okanye emva kokutyatyamba; ukulawula iintshulube, ukutshiza amayeza okubulala izitshabalalisi xa beseyimibungu emincinci. Ngokuqhelekileyo, i-60-80ml ye-40% ye-EC ixutywe kunye ne-30-45kg yamanzi ngehektare nganye; Ukulawula iintshulube ze-armyworms kunye neentwala, i-50-75ml ye-40.7% EC isetyenziswa kwi-acre enye kwaye i-40-50kg yamanzi iyatshizwa.
3. Umbona: Ngexesha lexilongo, sebenzisa i-80-100g ye-15% ye-granules ukuze usasaze kumagqabi entliziyo.
4. Izinambuzane zomqhaphu: Xa ulawula icotton aphid, iilygus bugs, thrips, weevils, kunye nezinambuzane ezakha ibhulorho, fafaza izibulali zinambuzane xa inani lezinambuzane lisanda ngokukhawuleza; xa ulawula iintshulube zecotton bollworms kunye nepink bollworms, fafaza amayeza okubulala izitshabalalisi ngexesha lokuqanduselwa kwamaqanda kwimibungu Tshaza phambi kokuba ugrumbe amagqabi. Ngokubanzi, fafaza i-100-150ml ye-40% ye-emulsifiable concentrate kunye ne-45-60kg yamanzi ngehektare nganye.
5. Iingcambu zeempethu zeliki kunye negalikhi: Kumanqanaba okuqala okwenzeka kwempethu yeengcambu, i-400-500ml ye-40% EC ngehektare nganye kufuneka inkcenkceshelwe ngamanzi okunkcenkceshela.
6. Ukulawula izinambuzane zomqhaphu, sebenzisa i-50 ml ye-40.7% chlorpyrifos EC ngehektare nganye kunye ne-40 kg yesitshizi samanzi. Kwizigcawu zomqhaphu, sebenzisa i-70-100 ml ye-40.7% ye-Lesbourne EC ngehektare nganye kwaye utshize nge-40 kg yamanzi. Khangela iSangqa sokuLima imifuno kwi-WeChat ukuze unikele ingqalelo. Kwi-cotton bollworm kunye ne-pink bollworm, sebenzisa i-100--169 ml ngehektare nganye kwaye utshize ngamanzi.
7. Izinambuzane eziphantsi komhlaba: ezifana ne-cutworms, i-grubs, i-wireworms, njl., nkcenkceshela isiseko sezityalo ngamaxesha angama-800-1000 we-40% EC ngehektare nganye.
8. Ukulawula izitshabalalisi zemithi yeziqhamo, i-citrus leafmites kunye ne-spider mites kufuneka itshizwe ngamaxesha angama-1000-2000 we-40.7% EC. Sebenzisa 400-500 amaxesha ulwelo isitshizi ukunyanga heartworms ipesika. Le dosi ingasetyenziselwa ukulawula amangolwane e-hawthorn spider mites kunye ne-apile spider mites.
9. Izitshabalalisi zemifuno: ezifana nemibungu yekhaphetshu, i-diamondback moths, i-aphids, i-thrips, i-whiteflies, njl njl.
10. Ukulawula izitshabalalisi zomoba, fafaza i-20 ml ye-40.7% EC ngamanzi ngehektare nganye ukulawula iintwala ezinoboya bomoba.
11. Ukulawula izinambuzane zemifuno, sebenzisa i-100-150 ml ye-40.7% chlorpyrifos EC ngehektare efafazwe ngamanzi.
12. Ukulawula izinambuzane zesoya, fafaza i-40.7% EC 75--100 ml ngamanzi ngehektare nganye.
13. Ukulawula izinambuzane ezicocekileyo, sebenzisa i-100-200 mg / kg yokutshiza kwiingcongconi zabantu abadala. Umthamo wamayeza ombungu yi-15-20 mg/kg emanzini. Kumaphela, sebenzisa i-200 mg/kg. Kwiintakumba, sebenzisa i-400 mg/kg. Sebenzisa i-100--400 mg/kg ukuthambisa okanye ukuhlamba amakhalane eenkomo ezincinci kunye neentakumba kumphezulu wemfuyo.
14. Ukulawula izitshabalalisi zomthi weti, sebenzisa isitshizi solwelo esinentelekelelo esebenzayo yamaxesha angama-300-400 kwijiyometrids yeti, amanundu eti, imibungu, amanundu aluhlaza, inyongo yeti, inyongo ye-orenji, kunye namangolwane aneendevu ezimfutshane. .
Kukho iindlela ezintathu eziphambili zokulawula izinambuzane nge-chlorpyrifos:
1. Tshiza. Nciphisa i-48% ye-chlorpyrifos EC ngamanzi kunye nesitshizi.
1. Sebenzisa amaxesha angama-800-1000 olwelo ukulawula imibungu ye-American spotted leafminer, i-tomato spotted flyminer, i-pea leafminer, i-leafminer yekhaphetshu kunye neminye imibungu.
2. Sebenzisa amaxesha angama-1000 olwelo ukulawula umbungu wekhaphetshu, iSpodoptera litura lervae, imibungu yenundu yesibane, i-melon borer kunye neminye imibungu kunye nemifuno yasemanzini.
3. Sebenzisa amaxesha angama-1500 esisombululo ukuthintela kunye nokulawula imibungu evuzayo yomgodi wamagqabi aluhlaza kunye nemibungu yebhore etyheli.
2. Ukunkcenkceshela ngeengcambu: Dilute 48% chlorpyrifos EC ngamanzi uze unkcenkceshele iingcambu.
1. Ngexesha lokuqala lokuzala kweempethu zeleek, sebenzisa ukukhanya kolwelo okuphindwe kayi-2000 ukulawula iimpethu zeleek, kwaye usebenzise iilitha ezingama-500 zamayeza angamalwelo ngehektare nganye.
2. Xa unkcenkceshela igalikhi ngamanzi okuqala okanye okwesibini, sebenzisa i-250-375 ml ye-EC ngehektare nganye kwaye usebenzise i-pesticide ngamanzi ukukhusela iingcambu zengcambu.
