What seed treatment can be used for beans to control downy mildew etc?Wakil XL
What is the target plant population for winter beans?18 plants/m2
What is the ideal drilling date for winter beans?Mid october - Late November
What is the ideal sowing depth for beans?12.5 cm
What pre-em herbicide active ingredient options are there for winter beans?Pendimethalin, Clomazone, Imazamox, Carbetamide, Propyzamide, Prosulfocarb (EAMU)
What post-em herbicide options are there for BLW? What is the latest timing for application?Bentazone up to 7 leaves unfolded
What post-em grassweed herbicide options are there? What is the latest timing for application?Cycloxydim up to 8 weeks prior to harvest
What is the target plant population for spring beans?35-40 plants/m2
What is the monitoring and control process for Bruchid Beetle?At early pod set look for adults, if found spray hallmark zeon in high water volume once temperatures have reached 20 degrees on 2 consecutive days. Repeat after 10 days if adults remain present.
When are black bean aphids likely to be an issue, what is the threshold and how may they be controlled?May-June when 5% of plants are infested. Can be controlled using Primicarb
The crop has symptoms of thickened twisted stems, brittle leaves, bronze petioles and blackened shriveled seed. What is causing this?Stem nematode
How long can stem nematode survive in the soil?10 years
How can stem nematode be controlled?Test seed, do not plant infected seed, do not plant into infected soils
What is a suitable fungicide for beans?Pyraclostrobin, boscalid, azoxystrobin
What can be applied to treat downy mildew?Metalaxyl (EAMU)
What moisture should beans be harvested at?16-20%
How is bruchid beetle damage caused?Adults lay eggs into pods, larvae hatch and burrow into bean, hatch into adult and bore their way out
Other than adult damage, why are pea and bean weevil so damaging to legumes?The adults lay eggs into soil, larvae hatch and feed on nitrogen fixing root nodules
What is the PGRO advice for a bruchid threshold?2 consecutive days of 20 degrees and above, if adult is found in crop when pods have first developed, apply lambdacyhalothrin and 7-10 days later if still present
What is the threshold for black bean aphid?10%, but if application is made at 5% infestation then better control of virus infection
What are the two viruses transmitted by black bean aphids?Bean leaf roll virus, bean yellow mosaic virus
What is the UK certification threshold for C2 seed aschocyta infection?1%
What is the home saved seed aschocyta infection threshold for use?3%
What variety has resistance to aschocyta?Wizard
How does pea and bean wilt and foot root rot inoculum survive overwinter?In the trash as chlamydospores
What is the control strategy for foot and root rot?Improve drainage, certified seed, rotation
What are high risk conditions for bean rust?Hot dry weather in July/ August at early flowering
What are management controls of bean rust?Green bridge removal, Signum at flowering and spray 3 weeks later if present
What are high risk conditions of chocolate spot?Windy, 15-20 degrees and humid, phosphate deficient soils
How does chocolate spot overwinter?Sclerotia in the soil and on volunteers
What are management controls of chocolate spot?Rotation, separate spring and winter crops, avoid new crops near old crop location, signum applied at flowering
What are high risk conditions of downy mildew?Cool humid weather, spring crops
How is downy mildew overwintered?Oospores in the soil
What are management controls of downy mildew?Remove crop debris, rotation, SL567A with signum at flowering
When is T1 for beans?Early/ mid flowering/ BBCH 59
When is T2 for beans?Mid/ late flowering/ BBCH 69
What is significant about the use of SL567A in beans?It has EAMU
Do any winter bean varieties have downy mildew resistanceNo
