Izinsalela zezibulala-zinambuzane ekudleni: sinjani isimo e-EU?
Embikweni wayo wakamuva waminyaka yonke, i-European Food Safety Authority (EFSA) ithe ingozi empilweni yabantu evela ezinsaleleni zezibulala-zinambuzane ezisetshenziselwa ukubulala noma ukulawula izinambuzane (kufaka phakathi izinambuzane ezithwala izifo kanye nezinambuzane eziyingozi, izilwane, nezitshalo) isalokhu iphansi, ihambisana neminyaka edlule. I-EFSA ihlaziye ...Funda kabanzi -
Bona ngeso lengqondo umphumela wezibulala-zinambuzane ekusebenzeni kwesiteshi se-TRP kanye nokuhlangana kwezinambuzane.
Izibulala-zinambuzane zidlala indima ebalulekile ekubhekaneni nokuntuleka kokudla emhlabeni wonke kanye nokulwa nezifo zabantu ezithwalwa yizinambuzane. Kodwa-ke, inkinga ekhulayo yokumelana nezibulala-zinambuzane idinga ngokushesha ukutholakala kwamakhemikhali amasha ahlose izinhloso ezingasetshenziswa kahle. Amandla okwamukela izinambuzane (i-TRPV) ...Funda kabanzi -

Unomthelela omkhulu ku-mycoplasma futhi unomphumela omuhle wokuvimbela amabhaktheriya athile, njengebhaktheriya ene-Gram-positive, amabhaktheriya ane-Gram-negative, nama-spirochetes, njll. Kuhlanganisa ne-Streptococcus pneumoniae, ...Funda kabanzi -
Isikhunta esibangela izifo ezinambuzaneni iBeauveria bassiana kanye neMetarhizium anisopliae zidlala indima ekukhuthazeni ukukhula kommbila (iZea mays).
I-Beauveria bassiana kanye ne-Metarhizium anisopliae ziyizinhlobo ezimbili zefungi ezibangela izifo (ama-EPF) ezibaluleke kakhulu futhi ezisetshenziswa kabanzi ekulawuleni izinambuzane. Izifundo zakamuva zikhombisile ukuthi zingakhuthaza nokukhula kwezitshalo ngemva kokugonywa okwenziwayo. Ukuze kuhlolwe ngokunembile ukwakheka kwamakoloni kanye nokukhula...Funda kabanzi -
Izikhwama zendwangu eziphathwe ngemithi yokubulala izinambuzane 'eshibhile kakhulu' zinganciphisa umalaleveva ezinganeni | Impilo Yomhlaba Wonke
Ucwaningo lukhombisile ukuthi ngenxa yokuthi ukulunywa omiyane kwenzeka kaningi emini, ukucwilisa izindwangu ngemithi evamile yokuxosha izinambuzane kuyindlela elula nephumelelayo. Kusukela e-Afrika kuya eLatin America, bese kuba se-Asia, amakhulu eminyaka omama bebesonga izingane zabo ngendwangu futhi bephatha...Funda kabanzi -
Izici eziyinhloko ezibangela ubuthi be-phytotoxicity
I. Izitshalo Izitshalo ezahlukene zibonisa amazinga ahlukene okumelana nokuzwela kuhlobo ngalunye lwezinambuzane. Izitshalo zinezinga elithile lokubekezelela izibulala-zinambuzane. Uma ukuhlushwa noma umthamo kudlula umkhawulo othile, ngokuvamile zizobhekana namazinga ahlukene omonakalo ovela ezibulala-zinambuzane. I ...Funda kabanzi -
Izici eziyinhloko kanye namasu okusebenzisa i-Chlorantraniliprole
