I-Matrine uhlobo lwesikhunta sezitshalo.Ikhishwa ezimpandeni, iziqu, amaqabunga nezithelo ze-Sophora flavescens.Isidakamizwa sinamanye amagama abizwa ngokuthi i-matrine ne-aphid.Umuthi unobuthi obuphansi, unezinsalela eziphansi, awuhambisani nemvelo, futhi ungasetshenziswa etiyeni, ugwayi nezinye izitshalo.

I-Matrine ingakhubaza isimiso sezinzwa esimaphakathi sezilokazane, ihlanganise amaprotheni ezinambuzane, ivimbele i-stomata yezinambuzane, futhi icindezele izinambuzane zife.I-Matrine inokuthinta kanye nemiphumela yobuthi esiswini futhi ingabulala izinhlobonhlobo zezinambuzane.

I-Matrine ilungele ukulawula izinambuzane ezincelisayo ezinjenge-aphid, futhi inemiphumela emihle yokulawula izibungu zeklabishi, amabhu e-diamondback, amacimbi etiye, ama-leafhopper aluhlaza, izimpukane, njll. Ngaphezu kwalokho, umuthi ubuye ube nemiphumela emihle yokulawula kwezinye izifo, njenge-anthracnose. , isikhutha kanye nesikhutha.

Njengoba i-matrine iyisibulala-zinambuzane esivela esitshalweni, umphumela wayo wokubulala izinambuzane uhamba kancane.Ngokuvamile, imiphumela emihle ingabonakala kuphela ezinsukwini ezingu-3-5 ngemva kokufakwa kwesicelo.Ukuze kusheshiswe umphumela osheshayo nohlala njalo womuthi, Ingahlanganiswa nezibulala-zinambuzane ze-pyrethroid ukuze ibe nomphumela ongcono wokulawula izibungu nama-aphid.

Ukulawula Izinambuzane:

1. Izinambuzane zamabhu: Ukulawulwa kwama-inchworm, amabhu anobuthi, amabhu esikebhe, amabhu amhlophe, nezibungu zikaphayini ngokuvamile kwenzeka phakathi nesigaba sesi-2-3 sezibungu, okuyinkathi ebucayi yokulimala kwalezi zinambuzane.

2. Ukulawula amacimbi.Ukulawula kuvame ukwenziwa lapho izikelemu sezineminyaka engu-2-3 ubudala, ngokuvamile cishe isonto ngemva kokuba abantu abadala bezalele amaqanda.

3. Ngezifo ze-anthrax ne-epidemic, i-matrine kufanele ifuthwe ekuqaleni kwesifo.

Amafomu omthamo ojwayelekile we-matrine:

0.3 i-matrine emulsifiable concentrate, 2% i-ejenti enamanzi ka-matrine, 1.3% i-ejenti enamanzi ka-matrine, 1% i-ejenti enamanzi ka-matrine, 0.5% i-ejenti yamanzi ka-matrine, 0.3% i-ejenti enamanzi ka-matrine, 2% encibilikayo, 1.5% encibilikayo, 1.5% 0.3% i-ejenti encibilikayo.

Izinyathelo zokuzivikela:

1. Akuvunyelwe ngokuphelele ukuxuba izibulala-zinambuzane ezine-alkaline, ukugwema ukukhanya okunamandla, nokusebenzisa izibulala-zinambuzane kude nezinhlanzi, izimfanzi, nezikelemu zikasilika.

2. I-Matrine inokuzwela okuncane kwezibungu ze-4-5 ezingaphakathi futhi ayisebenzi kakhulu.Ukusetshenziswa komuthi kusenesikhathi kufanele kuqashelwe ukuvimbela izinambuzane ezincane.
