Daun\u0103torii reprezint\u0103 un factor limitativ foarte important \u00een ceea ce prive\u015fte cultura de porumb. Unul dintre cei mai periculo\u015fi d\u0103un\u0103tori ce atac\u0103 porumbul este sfredelitorul porumbului (Ostrinia nubilalis).<\/p>\n
Insecticidul biologic BactoSpeine DF, poate fi folosit cu succes at\u00e2t \u00een tratamentele conven\u0163ionale, c\u00e2t \u015fi \u00een cele ecologice. Femelele de Ostrinia, depun ponta, ou\u0103 de culoare alb-sidefie, pe partea inferioar\u0103 a frunzelor, pe frunzele 3-8. Larvele aflate \u00een primele stadii de dezvoltare sunt mici \u015fi m\u0103soar\u0103 2-3 mm. Ulterior acestea intr\u0103 \u00een tulpini unde \u015fi produc cele mai mari pagube, s\u0103p\u00e2nd galerii, ce duc \u00een timp la fr\u00e2ngerea tulpinilor \u015fi favorizeaz\u0103 apari\u0163ia bolilor. Din cauza faptului c\u0103 zborul adul\u0163ilor are loc noaptea, acesta nu poate fi monitorizat \u00eendeaproape, monitorizarea se face urm\u0103rind mai mult larvele, \u00eendeosebi \u00een stadiile incipiente L1 \u2013 L3.<\/p>\n
Tratamentul cu BactoSpeine\u00ae DF se aplic\u0103 atunci c\u00e2nd se observ\u0103 primele larve, preferabil \u00een perioadele de hr\u0103nire activ\u0103. Tratamentele se repet\u0103 la intervale de 7 \u2013 10 zile, utiliz\u00e2nd o concentra\u0163ie minim\u0103 de produs de 100 g per 100 l apa\u0306. Doze m\u0103rite sunt necesare c\u00e2nd presiunea de atac este mare sau c\u00e2nd popula\u0163iile larvare sunt amestecate cu indivizi \u00een stadii avansate de dezvoltare.<\/p>\n
BactoSpeine\u00ae DF ac\u0163ioneaz\u0103 asupra larvelor d\u0103un\u0103torilor \u0163int\u0103 imediat dup\u0103 ce acestea consum\u0103 din plantele tratate. Pere\u0163ii intestinali \u00eencep s\u0103 se degradeze, larvele nu se mai pot hr\u0103ni \u015fi mor \u00een 24 \u2013 72 de ore. Eficacitatea produsului BactoSpeine\u00ae DF \u00een controlul larvelor tinere din ordinul Lepidoptera este asem\u0103n\u0103toare cu cea a insecticidelor conven\u0163ionale, administrate conform recomand\u0103rilor speciali\u015ftilor.<\/p>\n
