Hauv paus-knot nematodes yog cov kab hauv av tseem ceeb ntawm ntau cov qoob loo xws li txiv lws suav, txiv tsawb, txiv hmab txiv ntoo, txiv tsawb, dib, thiab lwm yam. Txij li cov hauv paus-knot nematodes feem ntau ua mob rau cov hauv paus hniav, tsis muaj cov tsos mob tshwm sim thaum ntxov, uas tuaj yeem tshwm sim. yooj yim yuav tsis meej pem nrog nutrient deficiency. Thaum pom cov tsos mob pom tseeb, kev tiv thaiv thiab kev tswj xyuas nyuaj heev. Qhov kev puas tsuaj ntawm cov hauv paus-knot nematodes rau cov nroj tsuag yog qhov thib ob tsuas yog cov kab mob fungi, thiab ntau dua qhov kev puas tsuaj ntawm cov kab mob thiab kab mob. Muaj ntau tus neeg sawv cev rau kev tiv thaiv thiab tswj cov hauv paus-knot nematodes. Qhov twg yog qhov kev ntseeg siab tshaj plaws? Hnub no kuv pom zoo ib yam tshuaj uas yog kev lag luam thiab siv tau zoo.
1. Taw qhia rau tus neeg sawv cev
Tus neeg sawv cev no yog Abamectin · Fosthiazate, uas yog ib qho sib xyaw ntawm abamectin thiab fosthiazate. Abamectin yog cov tshuaj lom neeg hauv paus-knot nematode tswj tus neeg saib xyuas nrog kev sib cuag thiab mob plab. Nws ua rau lub paj hlwb ntawm cov kab tsuag tua nematodes. Fosthiazate yog ib qho kev sib cuag thiab cov kab mob nematicide. Nws tuaj yeem cuam tshuam kev ua haujlwm ntawm nematodes ntawm koob tshuaj tsawg thiab tiv thaiv nematodes los ntawm invading cov hauv paus hniav.
Tom qab ob qho tib si sib xyaw, cov co-toxicity coefficient nce mus txog 216, uas muaj kev sib xyaw ua ke tseem ceeb. Nws muaj kev sib cuag thiab mob plab lom, zoo systemicity, thiab ib tug ntev ntev nyhuv. Tam sim no nws yog qhov pheej yig tshaj plaws thiab pheej yig nematicide.
2. Cov yam ntxwv tseem ceeb
(1) Kev nrawm nrawm: Abamectin · Fosthiazate muaj cov nyhuv ntxiv thiab ua rau lub paj hlwb ntawm nematodes. Thaum cov nematodes tuaj rau hauv kev sib cuag nrog tus neeg sawv cev, lawv yuav raug tshuaj lom tsis pub dhau 15 feeb thiab nres thiab ua rau muaj kev phom sij. Tam sim no nws yog tus ceev tshaj nematicide.
(2) Cov nyhuv ntev ntev: Abamectin · Fosthiazate yog qhov ruaj khov hauv cov av thiab tuaj yeem tua cov hauv paus-knot nematodes hauv av. Fosthiazate muaj kev ua haujlwm zoo. Tom qab absorbed los ntawm cov qoob loo cov hauv paus hniav, nws muaj peev xwm nyob twj ywm nyob rau hauv cov qoob loo lub cev rau lub sij hawm ntev kom ua tiav lub hom phiaj ntawm kev siv tshuaj tua kab tas mus li. Cov nyhuv ntev ntev tuaj yeem ncav cuag li 4 lub hlis, thiab qhov ntev tshaj plaws tuaj yeem ncav cuag 6 lub hlis.
(3) Kev nyab xeeb zoo: Abamectin · Fosthiazate muaj kev nyab xeeb rau cov qoob loo thiab yuav tsis ua rau phytotoxicity. Abamectin yog tshuaj tua kab macrolide nrog kev sib cuag thiab mob plab. Nws muaj kev nyab xeeb rau cov qoob loo thaum siv ntawm cov tshuaj pom zoo. Fosthiazate kuj yog ib qho zoo heev thiab tsis tshua muaj tshuaj lom organophosphorus nematicide uas yog qhov tseem ceeb thiab muaj kev nyab xeeb rau cov qoob loo.
(4) Tsawg toxicity thiab low residue: Abamectin · Fosthiazate yog ib qho chaw ntawm cov tshuaj lom neeg abamectin thiab cov tshuaj tua kab mob organophosphorus tsawg heev. Nws muaj cov pa phem me me rau cov av thiab dej hauv av, thiab tsis muaj tshuaj lom rau tib neeg thiab ib puag ncig cov kab mob. Nws yuav luag tsis muaj txiaj ntsig rau cov kab mob muaj txiaj ntsig hauv cov av.
3. Cov ntaub ntawv tseem ceeb
Abamectin · Fosthiazate muaj ntau hom tshuaj, cov ntaub ntawv tseem ceeb yog: 15%, 11%, 10.5%, 9%, 6%, 5%, 3% granules, 21%, 9% emulsions, 10% microemulsions.
4. Kev siv
(1) Kev kho av: Nyob rau hnub sowing, transplanting los yog cog qoob loo xws li txiv lws suav, dib, thiab watermelons, siv 2-4 kg / mu ntawm 11% Abamectin · Fosthiazate granules, sib tov cov granules nrog {{3} } kg ntawm nplua av los yog organic chiv, thiab siv los ntawm kev sib kis, furrowing los yog lub qhov. Tom qab tus neeg sawv cev sib xyaw nrog cov av, sow lossis hloov cov qoob loo, thiab tom qab ntawd dej.
(2) Kev kho hauv paus dipping: Hnub cog lossis hloov txiv lws suav, dib, txiv lws suav, thiab melons, dilute cov hauv paus hniav nrog 750 npaug ntawm dilution ntawm 21% Abamectin · Fosthiazate emulsion, ces cog thiab npog nrog av, uas muaj peev xwm tswj tau zoo dua. kev puas tsuaj ntawm cov hauv paus-knot nematodes.
(3) hauv paus irrigation: Nyob rau hauv thaum ntxov theem ntawm cov cag-knot nematode tshwm sim nyob rau hauv cov qoob loo xws li txiv lws suav, dib, luam yeeb, txiv hmab txiv ntoo, txiv tsawb, txiv tsawb, thiab melons, siv 500-1000 ml ntawm 21% Abamectin · Fosthiazate emulsion, Ntxiv 750 kg dej, sib tov zoo, thiab ces irrigate lub hauv paus. Siv 200-300 ml ntawm kev daws rau txhua tsob nroj kom ceev nrooj tswj kev puas tsuaj ntawm cov hauv paus-knot nematodes.
