Siv Cov Txheej Txheem
1. Rau zaubkev tswj kab tsuagntawm cov npauj npaim diamondback, siv 2.5% tus neeg sawv cev ncua 1000-1500 zaug ntawm cov tshuaj kom txau sib npaug hauv theem siab tshaj plaws ntawm cov menyuam yaus, lossis siv 2.5% tus neeg sawv cev ncua 33-50ml rau 20-50kg ntawm cov dej tsuag txhua 667m2.
2. Yuav kom tswj tau kab tsuag beet armyworm, tsuag dej nrog 2.5% suspension agent 50-100ml txhua 667 square meters thaum tseem tab tom loj hlob, thiab qhov zoo tshaj plaws yog thaum yav tsaus ntuj.
3. Txhawm rau tiv thaiv thiab tswj cov kab thrips, txhua 667 square meters, siv 2.5% suspension agent 33-50ml los tsuag dej, lossis siv 2.5% suspension agent 1000-1500 zaug ntawm cov kua los tsuag kom sib npaug, tsom mus rau cov ntaub so ntswg hluas xws li paj, txiv hmab txiv ntoo hluas, cov lus qhia thiab cov ceg.
Cov Lus Qhia
1. Tej zaum yuav muaj tshuaj lom rau ntses lossis lwm yam tsiaj txhu hauv dej, thiab yuav tsum tsis txhob ua kom cov dej thiab pas dej muaj kuab paug.
2. Khaws cov tshuaj rau qhov chaw txias thiab qhuav.
3. Lub sijhawm ntawm kev siv zaum kawg thiab sau qoob loo yog 7 hnub. Tsis txhob ntsib nag hauv 24 teev tom qab txau tshuaj.
4. Ua tib zoo saib xyuas kev nyab xeeb ntawm tus kheej. Yog tias nws nkag mus rau hauv qhov muag, yaug tam sim ntawd nrog dej ntau. Yog tias kov daim tawv nqaij lossis khaub ncaws, ntxuav nrog dej ntau lossis dej xab npum. Yog tias ua yuam kev, tsis txhob ua rau koj ntuav, tsis txhob pub dab tsi lossis ua rau ntuav rau cov neeg mob uas tsis tsaug zog lossis muaj mob qaug dab peg. Tus neeg mob yuav tsum raug xa mus rau tsev kho mob tam sim ntawd kom kho.
Txoj kev ua haujlwm
Lub tshuab ua haujlwm ntawm polycidin yog qhov tshiab thiab tshwj xeeb, uas txawv ntawm cov macrolides dav dav, thiab nws cov qauv tshuaj tshwj xeeb txiav txim siab nws cov txheej txheem tua kab tshwj xeeb. Polycidin muaj kev sib cuag sai thiab kev noj tshuaj lom rau kab. Nws muaj cov tsos mob tshwj xeeb ntawm cov neeg sawv cev ntawm cov hlab ntsha. Nws lub tshuab ua haujlwm yog los txhawb lub paj hlwb ntawm cov kab, ua rau nws cov haujlwm tsis tau npaj tseg, thiab ua rau cov leeg nqaij tsis ua haujlwm, ua tsis tiav, nrog rau kev co thiab tuag tes tuag taw. Nws tau pom tias nicotinic acetylcholine receptor (nChR) tau ua haujlwm tas li kom ua rau acetylcholine (Ach) tso tawm ntev. Polycidin kuj ua rau γ-aminobutyric acid (GAGB) receptors, hloov pauv kev ua haujlwm ntawm GABA gated chlorine channels thiab txhim kho nws cov haujlwm tua kab.
Txoj kev puas tsuaj
Cov tshuaj tua kab uas seem nyob hauv ib puag ncig yog hais txog "qhov siab tshaj plaws" ntawm cov tshuaj tua kab uas ib puag ncig muaj, uas yog, nyob rau hauv ib cheeb tsam thiab ib lub sijhawm, ob qho tib si kom ntseeg tau tias muaj txiaj ntsig zoo ntawm cov khoom ua liaj ua teb thiab tsis ua rau ib puag ncig zoo. "Qhov siab tshaj plaws" kuj yog tus nqi ntsuas qhov kev nyab xeeb ib puag ncig ntawm cov tshuaj tua kab, thiab nws kuj yog qhov hloov pauv uas maj mam txo qis nrog kev hloov pauv ntawm lub sijhawm thiab cov xwm txheej ib puag ncig. Tsuav nws tsis tshaj qhov ntsuas no, qhov kev nyab xeeb ib puag ncig ntawm cov tshuaj tua kab yog tsim nyog. Polycidin sai sai lwj hauv ib puag ncig los ntawm ntau txoj hauv kev sib xyaw ua ke, feem ntau yog photodegradation thiab microbial degradation, thiab thaum kawg lwj mus rau hauv cov khoom ntuj xws li carbon, hydrogen, oxygen, thiab nitrogen, yog li tsis ua rau muaj kuab paug rau ib puag ncig. Lub sijhawm photodegradation ib nrab ntawm polycidin hauv av yog 9 ~ 10 hnub, ntawm nplooj ntoos yog 1.6 ~ 16 hnub, thiab ntawm dej tsawg dua 1 hnub. Tau kawg, lub neej ib nrab yog cuam tshuam nrog lub zog ntawm lub teeb, thaum tsis muaj lub teeb, lub neej ib nrab ntawm multicidin los ntawm kev ua haujlwm hauv av aerobic yog 9 txog 17 hnub. Tsis tas li ntawd, cov av hloov pauv coefficient ntawm polycidin yog nruab nrab K (5 ~ 323), nws cov solubility hauv dej tsawg heev thiab tuaj yeem lwj sai, yog li qhov kev ua haujlwm leaching ntawm polycidin qis heev, yog li nws tsuas yog siv tau zoo, thiab nws kuj muaj kev nyab xeeb rau cov dej hauv av.
