Kugwiritsa Ntchito Heptafluthrin

Ndi mankhwala ophera tizilombo otchedwa pyrethroid, omwe ndi mankhwala ophera tizilombo m'nthaka, omwe amatha kulamulira bwino coleoptera ndi lepidoptera ndi tizilombo tina tomwe timakhala m'nthaka. Ndi 12 ~ 150g/ha, amatha kulamulira tizilombo tomwe timakhala m'nthaka monga pumpkin decastra, golden needle, jumping beetle, scarab, beet cryptophaga, ground tiger, corn borer, Swedish wheat stalk fly, ndi zina zotero. Ma granules ndi madzi opangidwa amagwiritsidwa ntchito pa chimanga ndi shuga beet. Njira yogwiritsira ntchito ndi yosinthasintha ndipo ingagwiritsidwe ntchito ndi zida wamba zobzala mbewu, nthaka yapamwamba ndi ngalande kapena kuchiza mbewu.

10% Heptafluthrin emulsion; 0.5%, 1.5% sefluthrin granules; 10% Heptafluthrin dry glue suspension. Imagwiritsa ntchito mankhwala ophera tizilombo otchedwa pyrethroid. Pochiza nthaka, imatha kuletsa coleoptera, lepidoptera ndi tizilombo tina tomwe timakhala m'nthaka, mlingo wake ndi 0.12 ~ 1.5g/100m2. Ingagwiritsidwenso ntchito ngati mankhwala ophera mbewu.

Heptafluthrin ndi mankhwala ophera tizilombo a pyrethroid othandiza kwambiri, ndipo ntchito yake imayang'ana kwambiri mbali zotsatirazi:

1. Cholembera cha mankhwala oletsa udzudzu: Heptafluthrin ndi yoyenera kwambiri pa mtundu watsopano wa cholembera cha mankhwala oletsa udzudzu chifukwa cha ntchito yake yambiri komanso kuthamanga kwa nthunzi. Mu chipangizo chotere, mankhwalawa amatulutsidwa mumlengalenga ndi mphamvu yachilengedwe ya mphepo, ndikupanga chotchinga choteteza chomwe chimathamangitsa kapena kupha udzudzu.

2. Mlingo wa fan: Mtundu wa fan womwe umagwiritsa ntchito mphamvu ya mphepo kuti usinthe mankhwalawo ndi gawo lofunika kwambiri la Heptafluthrin. Mankhwalawa amafalitsa mamolekyu a mankhwalawo ndi mphepo ndipo amatha kulamulira bwino tizilombo m'dera lalikulu.

3. Aerosol: Heptafluthrin ingagwiritsidwenso ntchito mu aerosol kuti iphimbe ndi kupha tizilombo mwachangu potulutsa tinthu ting'onoting'ono. Fomu iyi ya mlingo ndi yoyenera pochiza mwachangu mavuto a tizilombo m'nyumba kapena m'madera am'deralo.

4. Mankhwala oletsa udzudzu pogwiritsa ntchito magetsi/madzimadzi: Mu mankhwala oletsa udzudzu pogwiritsa ntchito magetsi kapena madzi, sevoflurthrin ingathandizenso potentha kutulutsa mankhwala, kupitiriza kuyendetsa kapena kupha udzudzu ndi tizilombo tina.
