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 resistance | No |
