3. Kudzivirira uye kudzora zvikwekwe zvedonje. Mushonga wedonje wespider une 1000~2000 times ye20% emulsifiable concentrate (effective concentration 100~200mg/kg Chemicalbook) panguva yekukwira kwemazai neshiri. 0.1-0.2mg/kg (yakaenzana ne2000-1000 times 20% emulsifiable concentrate). Uchishandiswa pakati nepakati pekukura kwedonje, unogona zvakare kushandiswa kudzora zvese zvikwekwe zvedonje neshiri dzemubollworm dzvuku.

4. Kudzivirira nekudzora zvikwekwe, zvikwekwe, nezvimwe zvipembenene zviri kunze kwezvipfuyo. Shandisai ka2000 ~ 4000 ka2 ...

Zvekungwaririra

1. Kana ikashandiswa munzvimbo dzinopisa uye dzine zuva uye tembiricha dziri pasi pe25 ℃, kushanda kweamitraz hakuna kunaka.

2. Hazvina kukodzera kusanganiswa nemishonga inouraya zvipembenene inonzi alkaline (yakadai seBordeaux liquid, sulfur compounds, nezvimwewo). Shandisa chirimwa ichi kusvika kaviri mumwaka wega wega. Usasanganisa neparathion yemiti yemaapuro kana yemapeya kudzivirira kukuvara kwemishonga.

3. Rega kushandisa mushonga we citrus mazuva makumi maviri nerimwe usati wakohwewa, uchishandisa mushonga we citrus ka1000 kupfuura mvura yacho. Rega kushandisa donje mazuva manomwe usati wakohwewa, uchishandisa mushonga we 3L/hm2 (20% difamiprid emulsifiable concentrate).

4. Kana ganda rikasangana, sukurudza nesipo nemvura nekukasika.

5. Kune kukuvara kwemashizha nematavi emichero mipfupi emaapuro eGolden Crown. Izvi zvakachengeteka kune vavengi vezvipembenene nenyuchi.
