Kusiyana pakati pePermethrin neDinofuran

I. Permethrin

1. Hunhu hwepakutanga

Permethrin mushonga wezvipembenene wakagadzirwa, uye chimiro chayo chemakemikari chine chimiro chayo chemakemikari epyrethroid. Kazhinji imvura ine mafuta isina ruvara kana yero yakajeka ine hwema hwakasiyana. Hainyungudike mumvura, inonyungudika nyore nyore muzvinhu zvinonyungudutsa, inogara kwenguva refu kana yatsvuka, asi inogona kuora kana paine alkaline.

2. Mashandisirwo Makuru

Mukurima: Inogona kushandiswa kudzora zvipembenene zvakasiyana-siyana zvekurima, zvakaita sezviri padonje, miriwo, miti yemichero nezvimwe zvirimwa.

Panyaya yekudzivirira zvipembenene zvine hutsanana: Ine simba rakanaka rekudzivirira zvipembenene zvine hutsanana zvakaita seumhutu, nhunzi, nhata neinda, uye inogona kushandiswa mukudzivirira zvipembenene mudzimba, munzvimbo dzeveruzhinji, nezvimwewo. Kuburikidza nenzira dzakadai sekupfapfaidza zvakasara, njodzi yekubereka zvipembenene uye kutapurirana kwezvirwere inogona kuderedzwa.

II.Dinotefuran

1. Hunhu hwepakutanga

Dinotefuraniri mumishonga yezvipembenene yechizvarwa chechitatu yeneonicotinoid. Inoonekwa seupfu huchena hwekristaro.

2. Mashandisirwo Makuru

Mukurima, inonyanya kushandiswa kudzora maaphids, maleafhopper, maplanthopper, mathrips, nhunzi chena uye mhando dzadzo dzinorwisa zvirimwa zvakasiyana-siyana zvakaita segorosi, mupunga, donje, miriwo, miti yemichero nemashizha efodya. Panguva imwe chete, inoshanda zvikuru pakurwisa zvipembenene zveColeoptera, Diptera, Lepidoptera nehomoptera. Inogonawo kushandiswa kudzora zvipembenene zvemumba zvakaita semapete. Isa mumakona kana mumipata umo mapete anowanzoonekwa, semumakaribhoni nemidziyo yemagetsi, uye shandisa mukana wekukwanisa kwayo kupinda mukati kuti uwane simba rekubvisa mapete.

III. Musiyano uripo pakati pePermethrin neDinofuran

1. Nezve chepfu

Nezvekuenzanisa huwandu hwechepfu hwezvinhu zviviri izvi, zvidzidzo zvakasiyana uye mamiriro ekushandiswa zvinogona kupa mhedzisiro yakasiyana. Zvidzidzo zvakaratidza kuti furosemide ine chepfu shoma uye inogona kushandiswa kwenguva yakareba. Zvisinei, cyfluthrin (yakafanana necyfluthrin) ine chepfu yakawanda uye haifanirwe kushandiswa kwenguva yakareba. Asi kuenzanisa chepfu pakati pecyfluthrin nefurfuramide kuchiri kuda tsvakiridzo yakasarudzika kuti ionekwe.

2. Nezve mashandiro ekuita

Permethrin inonyanya kukanganisa hurongwa hwekufambisa tsinga dzezvipembenene, ichivadzivirira kuti vasafambe zvakanaka uye pakupedzisira zvichikonzera kufa kwavo. Furfuran inoshanda nekukanganisa hurongwa hwemetabolism yemapete (tichitora mapete semuenzaniso, mashandiro ayo ekurwisa zvimwe zvipembenene akafanana), ichivadzivirira kuti vasakure uye vabereke zvakanaka. Inewo mhedzisiro yakanaka yekudzora zvipembenene zvinobaya-baya muromo uye inoratidza kushanda kwakanyanya kwekuuraya zvipembenene pamatanho mashoma kwazvo.

3. Nezvezvinangwa zvekudzivirira nekudzora

Permethrin inonyanya kushandiswa kudzora zvipembenene zvakaita seumhutu, nhunzi, nhata neinda. Mukurima, inogona kudzora zvipembenene zvakasiyana-siyana zvezvirimwa. Fumefon inonyanya kushandiswa kudzora aphids, leafhoppers, planthoppers nezvimwe zvipembenene zvinosveta pazvirimwa zvakasiyana-siyana. Inewo simba rakanaka rekudzora zvipembenene zvemumba zvakaita semapete. Uyezve, ine simba riri nani rekudzora zvipembenene zvakatanga kusabatwa ne nicotinoid agents.
