Iifungicide zesoya: Oko kufuneka ukwazi
Ndigqibe ekubeni ndizame amayeza okukhunta kwiimbotyi zesoya okokuqala kulo nyaka. Ndingayazi njani ukuba ndizama yiphi i-fungicide, kwaye ndifanele ndiyisebenzise nini? Ndingayazi njani ukuba iyanceda? Iqela labacebisi bezityalo abaqinisekisiweyo base-Indiana abaphendula lo mbuzo baquka uBetsy Bower, uCeres Solutions, uLafayette; uJamie Bultemei...Funda ngokugqithisileyo -
Bhabha
I-Fly, (umyalelo weDiptera), nayiphi na inani elikhulu lezinambuzane ezibonakaliswa kukusetyenziswa kwesibini samaphiko kuphela xa kubhabha kunye nokunciphisa isibini sesibini samaphiko sibe ngamaqhina (abizwa ngokuba zii-halteres) asetyenziselwa ukulinganisela. Igama elithi fly lisetyenziswa rhoqo phantse nakwesiphi na isinambuzane esincinci esibhabhayo. Nangona kunjalo, kwi-entomolog...Funda ngokugqithisileyo -
Ukumelana neMichiza
Ukumelana nokhula kubhekisa kubuchule obuzuzwe njengelifa be-biotype yokhula bokusinda kwi-herbicide apho uluntu lokuqala lwaluchaphazeleka khona.

Ukubulala iifungi
I-fungicide, ekwabizwa ngokuba yi-antimycotic, nayiphi na into enobuthi esetyenziselwa ukubulala okanye ukuthintela ukukhula kwe-fungi. I-fungicides ngokubanzi isetyenziselwa ukulawula i-fungi ebangelwa zi-parasitic ebangela umonakalo kwezoqoqosho kwizityalo okanye kwizityalo zokuhombisa okanye ebeka impilo yezilwanyana zasekhaya okanye yabantu emngciphekweni.

Izifo zezityalo kunye nezinambuzane
Umonakalo kwizityalo obangelwa kukukhuphisana nokhula kunye nezinye izinambuzane eziquka iintsholongwane, iibhaktheriya, iifungi, kunye nezinambuzane uyawuphazamisa kakhulu umkhiqizo wazo kwaye kwezinye iimeko unokutshabalalisa ngokupheleleyo isivuno. Namhlanje, isivuno sesityalo esithembekileyo sifumaneka ngokusebenzisa iintlobo ezimelana nezifo, izinto eziphilayo...Funda ngokugqithisileyo -
Iingenelo zeZibulali-zinambuzane zezityalo
Izinambuzane bezisoloko zixhalabisa ezolimo nakwiigadi zasekhitshini. Izinambuzane ezibulala iintsholongwane ezisebenzisa imichiza zichaphazela impilo ngendlela embi kakhulu kwaye izazinzulu zijonge phambili kwiindlela ezintsha zokuthintela ukutshatyalaliswa kwezityalo. Izinambuzane ezibulala iintsholongwane ezisebenzisa imichiza ziye zaba yindlela entsha yokuthintela izinambuzane ukuba zitshabalalise...Funda ngokugqithisileyo -

Abalimi baseKenya bajongene nokusetyenziswa kakhulu kwezibulali-zinambuzane
NAIROBI, Novemba 9 (Xinhua) — Umlimi oqhelekileyo waseKenya, kuquka nabo basezilalini, usebenzisa iilitha ezininzi zezibulali-zinambuzane minyaka le. Ukusetyenziswa kuye kwanda kule minyaka idlulileyo emva kokuvela kwezinambuzane ezintsha kunye nezifo njengoko ilizwe laseMpuma Afrika lijongene nemiphumo emibi yokutshintsha kwemozulu...Funda ngokugqithisileyo -
