Mutemo mutsva weBrazil wekudzora kushandiswa kwemishonga inouraya zvipembenene inonzi thiamethoxam muminda yenzimbe unokurudzira kushandisa nzira yekudiridza nemadonhwe emvura.

Munguva pfupi yapfuura, Brazilian Environmental Protection Agency Ibama yakaburitsa mitemo mitsva yekugadzirisa kushandiswa kwemishonga inouraya zvipembenene ine chinhu chinoshanda chinonzi thiamethoxam. Mitemo mitsva hairambidze kushandiswa kwemishonga inouraya zvipembenene zvachose, asi inorambidza kupfapfaidza nzvimbo dzakakura zvisina kururama pazvirimwa zvakasiyana-siyana nendege kana matrakita nekuti kupfapfaidza kunowanzo donha uye kukanganisa nyuchi nezvimwe zvinoparadzira zvirimwa munzvimbo inorarama mhuka.
Kune zvirimwa zvakaita senzimbe, Ibama inokurudzira kushandiswa kwemishonga inouraya zvipembenene inonzi thiamethoxam nenzira dzakanyatsoshandiswa dzakadai sekudiridza nemadonhwe emvura kudzivirira njodzi dzekudonha kwemvura. Nyanzvi dzezvekurima dzinoti kudiridza nemadonhwe emvura kunogona kushandisa mishonga inouraya zvipembenene zvakachengeteka uye zvinobudirira muzvirimwa zvenzimbe, Inoshandiswa kudzora zvipembenene zvikuru zvakaita seMahanarva fimbriolata, matermites Heterotermes tenuis, zvipembenene zvenzimbe (Diatraea saccharalis) uye zvipembenene zvenzimbe (Sphenophorus levis). Kukanganisa kushoma pazvirimwa.

Mitemo mitsva inojekesa kuti mishonga yekuuraya zvipembenene yethiamethoxam haichakwanisi kushandiswa mukurapa nzimbe kubva mufekitori. Zvisinei, mushure mekunge nzimbe yakohwewa, mishonga yekuuraya zvipembenene inogona kushandiswa muvhu kuburikidza nenzira dzekudiridza dzinodonha. Kuti dzidzivise kukanganisa zvipembenene zvinoparadzira nzimbe, zvinokurudzirwa kuti pave nemazuva makumi matatu nemashanu kusvika makumi mashanu pakati pekudiridza kwekutanga nekudiridza kunotevera.
Pamusoro pezvo, mitemo mitsva ichabvumidza kushandiswa kwemishonga yekuuraya zvipembenene yethiamethoxam pazvirimwa zvakaita sechibage, gorosi, soya nenzimbe, zvinoiswa zvakananga muvhu kana mashizha, uye pakurapa mbeu, pamwe nemamiriro chaiwo akadai semuyero wemuti uye zuva rekupera kwemuti zvichizotsanangurwa zvakanyanya.

Nyanzvi dzakataura kuti kushandiswa kwemishonga chaiyo yakadai sekudiridza nemadonhwe emvura hakungogone chete kudzora zvirwere nezvipembenene zviri nani, asiwo kuve nechokwadi chekuti mashandiro akachengeteka uye kuderedza simba rekushandisa kwevanhu, inova tekinoroji itsva inogara kwenguva refu uye inoshanda. Kana tichienzanisa nekushandisa spray, kudiridza nemadonhwe emvura kunodzivirira kukuvara kunogona kuitika nekuda kwekuyerera kwemvura kunharaunda nevashandi, uye kunobatsira nharaunda uye kunochengetedza mari uye kunoshanda zvakanyanya.
