Munguva pfupi yapfuura, Brazilian Environmental Protection Agency Ibama yakapa mitemo mitsva yekugadzirisa kushandiswa kwemishonga inouraya tupukanana ine inoshanda thiamethoxam.Mitemo mitsva iyi hairambidze kushandiswa kwemishonga iyi zvachose, asi inorambidza kumwayamwaya nenzira isiri iyo nzvimbo huru pazvirimwa zvakasiyana nendege kana matirakita nekuti pfapfaidzo iyi inotatarika uye inokanganisa nyuchi nezvimwe zvinotakura mukume mumhepo.
Pambeu dzakaita senzimbe, Ibama inokurudzira kushandiswa kwethiamethoxam ine mishonga yekuuraya zvipembenene nenzira dzemashandisirwo emhando dzakaita sedrip irrigation kudzivirira njodzi yekudonha.Nyanzvi munyaya dzezvekurima dzinoti drip irrigation inogona kushandisa mishonga yezvipembenene muzvirimwa zvenzimbe zvisina njodzi, Inoshandiswa kurwisa twumbuyu hombe seMahanarva fimbriolata, mujuru Heterotermes tenuis, nzimbe (Diatraea saccharalis) nechipfukuto chenzimbe (Sphenophorus levis).Kukanganisa kushoma pazvirimwa.
Mitemo mitsva iyi inoburitsa pachena kuti mishonga yekuuraya zvipembenene yethiamethoxam haichakwanise kushandiswa mufekitari kurapwa kwekemikari yezvinhu zvinopfuya nzimbe.Zvisinei, mushure mekunge nzimbe yakohwewa, mishonga yezvipembenene inogona kushandiswa paivhu kuburikidza nemadiridziro edrip irrigation.Kuti tisakanganise zvipembenene zvinotakura mukume, zvinokurudzirwa kuti mazuva 35-50 asare pakati pekudiridzira kwekutanga kwekudonha uye kunotevera.
Pamusoro pezvo, iyo mitemo mitsva ichabvumira kushandiswa kwemishonga ye thiamethoxam pazvirimwa zvakaita sechibage, gorosi, soya bhinzi nenzimbe, yakanangidzirwa paivhu kana mashizha, uye nekurapa kwembeu, nemamiriro ezvinhu akadai sedosi uye zuva rekupera. akajekeswa.
Vanamazvikokota vakaratidza kuti kushandiswa kwemushonga chaiwo wakaita sedrip irrigation haingori nani kudzora zvirwere netumbuyu, asi zvakare kuve nechokwadi chekuchengetedzwa kwekushanda uye kuderedza kupinza kwevanhu, inova tekinoroji itsva inoenderera uye inoshanda.Kuenzaniswa nekushanda kwekupfapfaidza, kudiridza kwedrip inodzivirira kukuvadza kungangoita kwemvura kukukurwa kune zvakatipoteredza nevashandi, uye inoshamwaridzana nenharaunda uye ine hupfumi uye inoshanda pazere.
