Ingaruka zikomeye kuri Dazomet 98% Tc

Gusaba

Imiti yica udukoko twinshi. Nematocide ifite imikorere ya fumigation irashobora kubora methyl isothiocyanate, formaldehyde na hydrogen sulfide mu butaka, kandi bigira ingaruka zica kuri rhizoma nematode, stem nematode na heteroderma nematode. Byongeye kandi, ifite udukoko twica udukoko, bactericidal na herbicidal, bityo irashobora kandi kuvura ibihumyo byubutaka, udukoko twangiza ndetse nicyatsi cya chenopodium, nka ibirayi rhizoctonia, udukoko twitwa polypteroptera, udukoko twa kowbeetles, Gicurasi scarab larvae nibindi. Ukoresheje ibice 98% by'ubutaka 750 ~ 900g / 100m2 ubutaka bwumucanga, 900 ~ 1050g / 100m2 ibumba nkubuvuzi bwubutaka, gukwirakwiza cyangwa gukoresha umwobo, Igitabo cya Chemical kirashobora kurwanya indwara yimboga nimbuto za nematode. Ifu yuzuye 75% 1125g / 100m2 irashobora gukoreshwa muguhashya indwara yibirayi nematode.
Ubutaka bwa fumigant, methyl thioisothiocyanate nematocide, ndetse no kuvura ibihumyo, ibyonnyi byo mu kuzimu hamwe n’ibyatsi bibi, bizwi kandi ko bizimangana vuba. Ibicuruzwa byangirika mu butaka kugirango bibe methylaminomethyl dithiocarbamate, hanyuma bikore methyl isothiocyanate. Irashobora kurwanya neza nematode hamwe nibihumyo byubutaka, nka bagiteri ya cataplexy, bagiteri ya filariya, fusarium, nibindi, kandi irashobora no kubuza gukura kwibyatsi byinshi. Ifite ingaruka nziza zo kugenzura kumpamba yumuhondo.

Uburyo bwo kwanduza

(1) Mbere yo gukoresha Dazomet, sukura imizi yigihingwa giheruka, hanyuma ushyireho ifumbire fatizo isabwa nigihingwa gikurikira.
(2) Menya neza ko ubuhehere bwubutaka bugera kuri 50-60% yubushobozi bwamazi yo mumurima, niba butujuje ubuziranenge, urashobora gutera amazi mumurima; Iminsi 3-5 nyuma yo kuhira, koresha imashini kugirango uhindure kandi umenagure ubutaka kugirango umenye neza ubutaka.
(3) Iyo ukoresheje Dazomet, ubushyuhe bukwiye bwubutaka ni 12-18 ° C, kandi byibuze ntibishobora kuba munsi ya 6 ° C.
(4) Koresha 25-40g ya Dazomet kuri metero kare y'ubutaka. Muri byo, gukoresha imyumbati, urusenda rwiza, urusenda rwa pepper ni 20-25kg / mu, gukoresha pariki y'inyanya ni 25-30kg / mu, naho gukoresha parike ya strawberry ni 15-20kg / mu.
. Niba imizi ipfundo rya nematode ibaye ikomeye, ubujyakuzimu bwo guhinga bugomba kuba 40cm, kandi hagomba gukoreshwa urugero rwo hejuru rwo gukoresha ibiyobyabwenge.

3. Gusaba bigira ingaruka cyane kubushyuhe bwubutaka nubushuhe nubutaka bwubutaka, imikoreshereze yubushyuhe bwubutaka igomba kuba hejuru ya 12 ° C, 12-30 ° C niyo ikwiye cyane, ubuhehere bwubutaka burenze 40% (ubuhehere bwubutaka bwintoki burashobora gukora itsinda, uburebure bwa metero 1 burashobora gutatanwa nyuma yo kugwa kubutaka nkuko bisanzwe).
