Uburyo nyamukuru bwo kurwanya udukoko nindwara nyuma yo gusarura icyayi

Mugihe cyicyayi cyimpeshyi, imbeho yumukara ikuze itumba mealybugs ikunze kugaragara, udukoko twatsi tuboneka cyane mubice bimwe byicyayi, kandi aphide, caterpillars yicyayi hamwe nicyayi cyicyatsi kiboneka muke. Kurangiza gutema umurima wicyayi, ibiti byicyayi byinjira mucyayi cyizuba.

Ubuhanuzi bwihariye bwibiza byangiza udukoko hamwe nibyifuzo byo gukumira no kugenzura ingamba tekinike ni izi zikurikira:

Icyayi cyicyatsi kibisi: Kugeza ubu, benshi muribo bari mumyaka 2 kugeza 3. Umubare wibibaho muri iki gisekuru ni muto kandi nta kugenzura imiti itandukanye ikenewe. Mubibanza bibera icyayi cyicyatsi kibisi,imashini ifata udukokoirashobora kumanikwa mu mpera za Gicurasi kugirango ikumirwe kandi igenzurwe, amaseti 1-2 kuri mu; mu busitani bwicyayi aho hashyizweho amatara yica udukoko, birakenewe ko uhita ugenzura niba amatara yica udukoko akora neza.

Icyayi kibabi kibisi: Ubushyuhe nubushuhe birakwiriye mugihe cyizuba. Icyayi icyatsi kibisi cyororoka vuba. Igihe cyo kumera icyayi cyizuba kizinjira mugihe cyambere cyambere. Birasabwa kumanika 25-30Udukokonyuma yo gutema kugirango ugenzure umubare wabaturage b’udukoko no kugabanya impinga; nymphs Kubusitani bunini bwicyayi, birasabwa gutera 0.5% veratrum rhizome ikuramo, matrine, Metarhizium anisopliae nibindi binyabuzima; kugenzura imiti, buprofen, dinotefuran, acetamiprid, sulfonicamid, na acetamiprid irashobora gukoreshwa Imiti nka amide, indoxacarb, difenthiuron, na bifenthrin yanditswe kubiti byicyayi.

Icyayi cy'inyenzi: Ibinyomoro by'icyayi bikonje cyane mu busitani bw'icyayi bwo mu majyepfo ya Jiangsu byagaragaye bwa mbere ku ya 9 Mata, ubu bikaba biri mu cyiciro cy'abana. Biteganijwe ko abantu bakuru bazatangira kwigaragaza ku ya 30 Gicurasi hanyuma binjire mu cyiciro cya mbere ku ya 5 Kamena. Igihe cyo hejuru kizaba ku ya 8-10 Kamena. Umunsi; mu busitani bwicyayi nibintu bike, imitego yimibonano mpuzabitsina caterpillar irashobora kumanikwa mumpera za Gicurasi kugirango umutego wice abantu bakuru. Igihe ntarengwa cyo gufata icyayi cya caterpillar yo mu gisekuru cya kabiri giteganijwe kuba 1-5 Nyakanga. Ubusitani bwicyayi bwanduye cyane burashobora kugenzurwa no gutera Bacillus thuringiensis mugihe cyambere cya liswi (mbere ya 3 instar); imiti yica udukoko irashobora kuba cypermethrine, deltamethrine, hamwe na Phenothrine hamwe nindi miti yatewe hakoreshejwe aicyayi cyubusitani.

Mite: Ubusitani bwicyayi bwiganjemo icyayi orange gall mite mu cyi. Gukata nyuma yicyayi cyimpeshyi kirangiye bikuraho umubare munini wa mite, bigabanya neza umubare wibyabaye mugihe cyambere cyambere. Hamwe no kumera kwicyayi cyimpeshyi, umubare wibibaho wiyongera buhoro buhoro. Kugirango ugenzure neza ibibaho byangiza, nyuma yigiti cyicyayi kimaze kumera, urashobora gukoresha amavuta yubutare arenga 95% ukurikije dosiye isabwa, cyangwa ugakoresha ibimera bya veratrum rhizome, azadirachtin, pyroprofen nindi miti kugirango ubigenzure.

Birasabwa ko hashingiwe ku kugenzura ibidukikije mu busitani bw’icyayi, gushyira mu bikorwa ingamba zo kurwanya udukoko nko kurwanya umubiri naIcyayigutema bigomba gushimangirwa, kandi imiti yica udukoko twangiza imiti nudukoko twangiza udukoko twangiza udukoko twangiza udukoko mu bihe bikomeye.
