Tej yam tseem ceeb uas koj yuav tsum paub txog Abamectin yog dab tsi?

Abamectinfeem ntau yog siv los tswj Plutella xylostella, Pieris rapae, Spodoptera exigua, Spodoptera litura, leafminers, leaf rollers, Manduca sexta, root-knot nematodes, aphids thiab ntau yam kab tsuag. Nws txoj kev ua haujlwm yog txhawb kev tso tawm ntawm γ-aminobutyric acid (GABA), uas tiv thaiv cov hlab ntsha hauv cov kab tsuag, thaum kawg ua rau kab tsuag tuag tes tuag taw, tsis noj mov thiab tuag.

Cov Kab Tsuag uas Muaj Kev Tswj Zoo Tshaj Plaws ntawmAbamectin

1. Kev Tswj Kab Tsuag

Abamectin siv tau los tswj Plutella xylostella, Pieris rapae, cov nplooj miners, Liriomyza spp., Spodoptera exigua, Spodoptera litura, Phyllonorycter ringoniella, npauj npaim leafminer, npauj npaim leaf roller, Heliothis virescens, Manduca sexta, nematodes hauv paus, aphids thiab txhua yam kab tsuag (xws li Hawthorn Spider Mite, European Red Mite, Two-spotted Spider Mite, Citrus Red Mite, Rust Mite, Pear Psylla, thiab lwm yam).

2. Hom Kev Ua Haujlwm

Abamectin tsom mus rau GABAA receptors ntawm neuronal synapses lossis neuromuscular synapses ntawm cov kab, cuam tshuam kev xa cov teeb liab ntawm cov hlab ntsha kab. Nws ua rau cov hlab ntsha tso tawm cov neurotransmitter inhibitor γ-aminobutyric acid (GABA), ua kom GABA-gated chloride ion channels ua haujlwm thiab ua kom lawv qhib ntev dua. Kev nkag mus ntau ntawm chloride ions ua rau hyperpolarization ntawm lub zog ntawm cov hlab ntsha, ua rau cov hlab ntsha nyob rau hauv lub xeev inhibitory. Qhov no thaiv kev sib txuas lus teeb liab ntawm cov hlab ntsha thiab cov leeg, ua rau tuag tes tuag taw, tsis noj mov thiab tuag ntawm cov kab tsuag.

Cov Txheej Txheem Siv Abamectin

1. Rau kev tswj cov npauj npaim diamondback (Plutella xylostella) thiab cov kab mob zaub qhwv uas xa tuaj rau txawv teb chaws (Pieris rapae): Tsuag cov tshuaj sib tov ntawm 2% Abamectin EC diluted 1000–1500 zaug + 1% Emamectin Benzoate diluted 1000 zaug thaum lub sijhawm tseem hluas.
2. Rau kev tswj cov kab tsuag uas nrhiav nplooj txiv apple, cov npauj npaim nrhiav nplooj, cov yoov uas nrhiav nplooj, cov kab tsuag American serpentine thiab cov yoov dawb: Tshuaj tsuag 1.8% Abamectin EC diluted 3000–5000 zaug sib xyaw nrog cypermethrin ua haujlwm zoo diluted 1000 zaug thaum lub sijhawm qe ntau tshaj plaws thiab lub sijhawm kab tawm.
3. Rau kev tswj cov kab mob beet armyworm (Spodoptera exigua): Tshuaj tsuag 1.8% Abamectin EC diluted 1000 zaug.
4. Rau kev tswj cov kab laug sab, cov kab laug sab daj, cov kab laug sab gall thiab cov aphids ntawm cov ntoo txiv hmab txiv ntoo, zaub thiab cov qoob loo nplej: Tshuaj tsuag 1.8% Abamectin EC diluted 4000–6000 zaug.
5. Rau kev tswj cov kab mob nematode ntawm cov hauv paus zaub: Muab cov hauv paus ntub nrog 500 mL ntawm 1.8% Abamectin EC diluted nrog dej ib mu.
6. Rau kev tswj cov kab mob paj rwb (Helicoverpa armigera): Muab 60 mL ntawm 1.8% Abamectin EC sib tov nrog 50–60 kg dej rau ib mu thiab tsuag kom huv si thaum lub sijhawm qe tawm ntau tshaj plaws.
7. Rau kev tswj cov kab pear psylla: Tsuag 1.8% Abamectin EC diluted 6000–8000 zaug.
8. Rau kev tswj cov kab tsuag hauv paj, cov kab me me thiab cov kab thrips: Dilute 30–50 mL ntawm 1.8% Abamectin EC nrog dej rau ib mu thiab tsuag.
9. Rau kev tswj hwm ntawm cov nplooj mov dov (Cnaphalocrocis medinalis): Muab 30–45 mL ntawm 2.2% Abamectin EW nrog dej rau ib mu thiab tsuag.
