Kodi pali mankhwala udzu

wamaluwa zonse, wamaluwa, munda ogwira ntchito ndi alimi mdani chimodzi - udzu. zomera kukula kulikonse, makamaka pamene si koyenera. M'minda, minda ya zipatso ndi minda masamba namsongole othinana mbewu, zouma ndi impoverish nthaka, anasonkhanitsa chinyezi ndi chakudya mbewu ndipo kungakhale kovuta kuti mukololedwe. Komanso, moyo tizilombo toyambitsa matenda osiyana ndi tizilombo, omwe kawirikawiri adwale ndi zomera anabzala ndi munthu. Mwachidule, kupewa namsongole ndi kumvutitsa aliyense ndi nyonga zawo angakhoze kokha nsanje.

Koma sayansi Kodi kugona. Asayansi atulukira njira zosiyanasiyana namsongole kuthandiza polimbana ndi iwo. Namsongole, ndithudi, amapeza njira makina. kulima ichi, lalikulu, kulima, ndi dzanja-Kupalira. Agronomists zimagwilanso nchito kasinthasintha. Ndipo njira izi nthawi zina kudzathandiza kuchotsa zomera zapathengo, koma posakhalitsa. Komabe, pali njira zambiri - izo herbicides.

M'dera lino, sayansi wandipitirira kutali. Mwachitsanzo, kudzera mwa "mphepo yamkuntho" namsongole. Mothandizidwa ndi herbicide izi zikhoza idzachitikira bwinobwino ndi mitundu yoposa 150 namsongole osatha ndi pachaka. Pambuyo mankhwala ndi "mphepo yamkuntho", ambiri a iwo sizimaoneka nyengo lonse kukula. Ndipo pa maudzu pachaka kuti herbicide zotsatira za masiku 20 60 pamaso mpaka iwo proizrastut kwa mbewu.

Pali njira inanso namsongole pansi pa dzina "Roundup". Izi ndi mankhwala chilengedwe chonse zimene amachita pa maudzu iliyonse. Izo ntchito kulikonse. Kukonza "Roundup" ntchito monga zokhudza zonse herbicide yopitirira. Ndipo iwo ankachitira m'dera anakhumba ngakhale pamaso kufesa kapena, pafupifupi, pamaso zikamera. Pankhaniyi, ntchito nthaka, iye alibe, ndipo amachita kokha pa zanthete ndi masamba. Komanso, mankhwala "Roundup" imatengedwa kukhala otetezeka anthu ngati ntchito mogwirizana ndi malangizo.

Ndipo ngati weedkiller imeneyi imagwira pamaso kubzalako, lidzaonetsetsa chiwonongeko chotheratu cha namsongole osatha ndi pachaka, dicotyledonous ndi monga chimanga. Ndi herbicide "Roundup" Pankhaniyi adzachita pansi ndi mobisa mbali ya namsongole popanda nthaka zaderzhivayas. Pansi amalakatika ntchito yake ndi linawola pa zinthu zachilengedwe.

Palinso njira namsongole ndi dzina sonorous "Agrokiller". Mothandizidwa ndi mzimuwo kuwononga ndi namsongole dicotyledonous udzu, osatha ndi pachaka. Komanso, mankhwala "Agrokiller" amathandiza nkhondowo mitengo udzu ndi zitsamba. herbicide Ichi ndi mankhwala a ambiri Wankhondo kanthu. Ndipo tsopano palibe zomera (kupatula transgenic) chomwe chilibe phindu. Ndipo pamene ntchito bwino herbicide izi si poizoni kuti dziko nyama.

Chabwino weedkiller "Lapis" lakonzedwa kuthana ndi monga chimanga ndi dicotyledonous, pachaka ndipo osatha namsongole kubzala wa Solanaceae - tomato ndi mbatata. Ndipo herbicide izi kwa mbatata ndi tomato si asalankhule. Thiabendazole angagwiritsidwe ntchito kwa miyezi 1-2 ndi zambiri kuteteza chiyero cha mbewu ya namsongole. Mankhwala "Lapis" ingagwiritsidwe pamaso namsongole kuonekera. Kenako kuwawononga iwo pa siteji ya kukula. Komanso, iwo angathe kukonzedwa namsongole kale utakula. Pankhaniyi, amatanthauza "Lapis" muyenera masiku 10-20 kuwawononga.
