Kodi ndi zinthu ziti zofunika zomwe muyenera kudziwa zokhudza Abamectin?

AbamectinAmagwiritsidwa ntchito kwambiri polimbana ndi Plutella xylostella, Pieris rapae, Spodoptera exigua, Spodoptera litura, leafminers, leaf rollers, Manduca sexta, root-knot nematodes, aphid ndi tizilombo tosiyanasiyana. Njira yake yogwirira ntchito ndikulimbikitsa kutulutsidwa kwa γ-aminobutyric acid (GABA), yomwe imaletsa kufalikira kwa mitsempha mwa tizilombo, zomwe pamapeto pake zimapangitsa kuti tizilombo tizifa, kusiya kudya komanso kufa.

Tizilombo tomwe tili ndi mphamvu zowongolera bwinoAbamectin

1. Kuwongolera Tizilombo

Abamectin ingagwiritsidwe ntchito polimbana ndi Plutella xylostella, Pieris rapae, leaf miners, Liriomyza spp., Spodoptera exigua, Spodoptera litura, Phyllonorycter ringoniella, leafminer moths, leaf roller moths, Heliothis virescens, Manduca sexta, root-knot nematodes, aphids ndi mitundu yonse ya tizilombo toyambitsa matenda (kuphatikizapo Hawthorn Spider Mite, European Red Mite, Two-spotted Spider Mite, Citrus Red Mite, Rust Mite, Pear Psylla, ndi zina zotero).

2. Njira Yochitira Zinthu

Abamectin imayang'ana ma GABAA receptors pa neuronal synapses kapena neuromuscular synapses ya tizilombo, zomwe zimasokoneza kutumiza kwa zizindikiro pa malo olumikizirana mitsempha ya tizilombo. Imathandizira malo olumikizirana mitsempha kuti atulutse choletsa cha neurotransmitter γ-aminobutyric acid (GABA), imayendetsa njira za chloride ion zomwe zimalowa mu GABA ndikuwonjezera nthawi yotsegulira. Kuchuluka kwa ma chloride ion kumayambitsa hyperpolarization ya kuthekera kwa nembanemba ya mitsempha, ndikusunga nembanemba ya mitsempha mu mkhalidwe woletsa. Izi zimalepheretsa kulumikizana kwa zizindikiro pakati pa malo olumikizirana mitsempha ndi minofu, zomwe zimapangitsa kuti ziwalo zife, kuletsa kudya ndi kufa kwa tizilombo.

Njira Zogwiritsira Ntchito Abamectin

1. Kulamulira njenjete ya diamondback (Plutella xylostella) ndi nyongolotsi ya kabichi yochokera kunja (Pieris rapae): Thirani chisakanizo cha 2% Abamectin EC yochepetsedwa nthawi 1000–1500 + 1% Emamectin Benzoate yochepetsedwa nthawi 1000 pa siteji ya mphutsi zazing'ono.
2. Pofuna kuletsa tizilombo toyambitsa matenda a apulo, tizilombo toyambitsa matenda a leafminer, tizilombo toyambitsa matenda a leafminer, tizilombo toyambitsa matenda a American serpentine leafminer ndi whitefly: Thirani 1.8% Abamectin EC yochepetsedwa ka 3000–5000 yosakaniza ndi cypermethrin yochepetsedwa ka 1000 panthawi yoswa mazira komanso nthawi ya kufalikira kwa mphutsi.
3. Kuletsa nyongolotsi ya beet armyworm (Spodoptera exigua): Spray 1.8% Abamectin EC yochepetsedwa ka 1000.
4. Pofuna kuletsa akangaude, nthata za tiyi zachikasu, nthata za ndulu ndi nsabwe za m'masamba pamitengo ya zipatso, ndiwo zamasamba ndi mbewu za tirigu: Thirani 1.8% Abamectin EC yochepetsedwa nthawi 4000–6000.
5. Pofuna kuletsa matenda a mizu ya zomera: Thirani mizu ndi 500 mL ya 1.8% Abamectin EC yochepetsedwa ndi madzi pa mu.
6. Kuthana ndi nyongolotsi za thonje (Helicoverpa armigera): Sakanizani 60 mL ya 1.8% Abamectin EC ndi madzi okwana 50–60 kg pa mu ndipo thirani bwino nthawi yonse yoswa mazira.
7. Pofuna kuletsa peyala ya psylla: Thirani 1.8% Abamectin EC yochepetsedwa nthawi 6000–8000.
8. Pofuna kuletsa nsabwe za m'maluwa, tizilombo ta mamba ndi tizilombo ta thrips: Sakanizani 30–50 mL ya 1.8% Abamectin EC ndi madzi pa muga imodzi ndipo thirani.
9. Kuwongolera chopukutira cha masamba a mpunga (Cnaphalocrocis medinalis): Sakanizani 30–45 mL ya 2.2% Abamectin EW ndi madzi pa mu imodzi ndipo thirani.
