Gahunda yo guca nyakatsi yo mu murima:
Kurandura umurima wibishyimbo bishyigikira gutunganya ubutaka nyuma yo kubiba na mbere yingemwe.Turashobora guhitamo 0.8-1L 960 g / L Metolachlor EC kuri hegitari,
cyangwa 2-2.5L 330 g / L Pendimethalin EC kuri hegitari nibindi
Hejuru y'ibyatsi bigomba guterwa ku butaka nyuma yo kubibwa ibishyimbo na mbere yo kugaragara, kandi ibishyimbo bigomba gutwikirwa na firime nyuma yo kubisaba.
Mugihe cyo kuvuka nyuma yo kuvuka no kuvura amababi, ml 300-375 kuri hegitari ya 15% Quizalofop-Ethyl EC, cyangwa 300-450 ml kuri hegitari 108 g / L Haloxyfop-P-ethyl EC irashobora gukoreshwa mumababi 3-5 icyiciro cy'ibyatsi bibi;
Mugihe cyibibabi 2-4 byibyatsi, 300-450 ml kuri hegitari ya 10% Oxyfluorfen EC irashobora gukoreshwa mugutera imiti mugiti cyamazi namababi.
Gahunda yo kugenzura ihuriweho mugihe cyikura
1. Igihe cyo kubiba
Igihe cyo kubiba ni igihe gikomeye cyo kurwanya neza udukoko n'indwara zitandukanye.Ikibazo nyamukuru nukuvura no gukumira imbuto, ni ngombwa cyane guhitamo imikorere myiza, uburozi buke, hamwe nudukoko twangiza udukoko twangiza igihe kirekire kugirango twirinde indwara zanduza nudukoko twangiza.
Turashobora guhitamo 22% Thiamethoxam + 2% Metalaxyl-M + 1% Fludioxonil FS 500-700ml ivanze nimbuto 100kg.
Cyangwa 3% Difenoconazole + 32% Thiamethoxam + 3% Fludioxonil FS 300-400ml ivanze nimbuto 100kgs.
Ahantu udukoko twangiza cyane turashobora guhitamo 0.2%
Clothianidin GR 7.5-12.5kg .Bisaba mbere yo kubiba ibishyimbo, hanyuma ubibe nyuma yo gukuramo ubutaka neza.
Cyangwa 3% Phoxim GR 6-8kg, gusaba mugihe ubiba.
Imbuto zambaye cyangwa zisize zigomba kubibwa nyuma yo kumisha ikoti ryimbuto, byaba byiza mugihe cyamasaha 24.
2．Mu gihe cyo kumera mugihe cyindabyo
Muri iki gihe, indwara nyamukuru ni ibibabi, kubora imizi n'indwara ibora.Turashobora guhitamo 750-1000ml kuri hegitari ya 8% Tebuconazole + 22% Carbendazim SC, cyangwa 500-750ml kuri hegitari ya 12.5% Azoxystrobin + 20% Difenoconazole SC, gutera mugihe cyambere cyindwara.
Muri iki gihe, udukoko twinshi ni Aphis, Pamba bollworm nudukoko twangiza.
Kurwanya aphide na bollworm, dushobora guhitamo 300-375ml kuri hegitari ya 2,5% ya Deltamethrin EC, gutera mugihe cyambere cya Aphis nicyiciro cya gatatu cya instar ya pamba.
Kurwanya udukoko twangiza, dushobora guhitamo 1-1.5 kg ya 15% Chlorpyrifos GR cyangwa 1.5-2kg ya 1% Amamectin + 2% Imidacloprid GR, gutatanya.
3．Ibihe byigihe cyigihe cyo gukura kwimbuto
Gusaba kuvanga (udukoko twica udukoko + fungiside + igenzura imikurire yikimera) birasabwa mugihe cyo gushiraho ibishyimbo byibishyimbo, bishobora kurwanya neza indwara nudukoko dutandukanye mugihe cyo hagati na nyuma, bikarinda imikurire isanzwe yibibabi byibishyimbo, bikarinda gusaza imburagihe, kandi kuzamura gukura.
Muri iki gihe, indwara nyamukuru ni ibibabi, kubora, kurwara ingese, udukoko twinshi ni pamba bollworm na aphis.
Turashobora guhitamo 300-375ml kuri hegitari ya 2,5% Deltamethrin + 600-700ml kuri hegitari ya 18% Tebucanozole + 9% Thifluzamide SC + 150-180ml ya 0.01% Brassinolide SL, Gutera.
