Thiamethoxam: Assessing flight activity of honeybees foraging on treated oilseed rape using RFID technology
This study was designed to assess homing behaviour of bees foraging on winter oilseed rape grown from seed treated with thiamethoxam (as Cruiser OSR) with one field drilled with thiamethoxam treated seed and two control fields drilled with fungicide‐only treated seed. Twelve honeybee colonies were used per treatment group, 4 each located at the field edge (on‐field site), at approximately 500m ...

Accumulation and translocation of 198Hg in four crop species
The uptake and transport of mercury (Hg) through vegetation play an important role in the biogeochemical cycling of Hg. However, quantitative information regarding Hg translocation in plants is poorly understood. In this study, Hg uptake, accumulation and translocation in four corps rice (Oryza.sativa L.), wheat (Triticum L.), corn (Zea mays L.) and oilseed rape (Brassica campestris L.) grown ...

Behavioural and chemical ecology underlying the success of turnip rape (Brassica rapa) trap crops in protecting oilseed rape (Brassica napus) from the pollen beetle (Meligethes aeneus)
There is increasing interest in the use of trap crops as components of integrated pest management (IPM) strategies. Understanding the mechanisms underlying host plant preferences of herbivorous pests can lead to improved effectiveness and reliability of the trap crop. We investigated the behavioural and chemical ecology underlying the success of turnip rape, Brassica rapa, trap crops in ...

Drones and scissors help decide fertilizer rate
Both Swedish and European field trials show that winter oilseed rape that has taken up a lot of nitrogen in autumn needs less nitrogen in the spring. A thinner crop, which has not assimilated so much nitrogen in the autumn, needs more N fertilizer in the spring. In order to determine the autumn’s nitrogen uptake, the so-called “cutting method” is often used in Sweden. Drones ...

Wholesale arable change leads to tight slug control
"Eight years into implementing a zero-till policy across the farm, we’re seeing improved yields of 10 tonnes per hectare for our first year wheat, and five tonnes per hectare on winter beans. We’ve also noticed that we continue to see year-on-year improvements to soil structure and crop yields. “The winter beans have been extremely valuable in the rotation to ensure nitrogen ...

Seedbed preparation
Timing and weather, as well as kit, are key parts of seedbed preparation on the min-till system. The search for lower establishment costs has led one Warwickshire grower to ditch the plough and opt for a min-till approach that offers the capability to direct drill too. Geoff Ashcroft looks at the system in use. The ability to direct drill cereals does hold a certain appeal, particularly when ...

Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.
Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, particularly in ...

Local advice on managing blackgrass
Blackgrass is a weed that troubles many, and controlling it is an increasing challenge, particularly with the small armoury of products available, and the growing issue with resistance. Paul Drinkwater, Crop Production Manager for Abbots Ripton Farming Company, explains how, in his 40 years of being in the Cambridgeshire area, the blackgrass problem has evolved. “My role sees me manage ...

Proactive approach to slug control recommended to potato growers
If left untreated, slugs can cost the potato industry £53 million each year. With predictions of a high pressure slug season ahead, and the potential damage these pests can do to a crop both physically and financially, Robert Boothman, commercial director of Boothmans Agriculture, explains how to keep one step ahead of the pest. “The milder, wet winter and lack of ground frosts ...

Drill decision proves right one for suffolk farmer
When Peter Norman of B E Norman & Sons, Hall Farm, Wisset, Nr Halesworth, ordered his new 4 metre DP400A Moore drill in May 2004, he had never even seen one in the flesh. “I liked the look of the coulter system” he said “and knew that because it was in effect, a similar principle of depth control to a sugar beet drill, but much more heavy duty, it would easily cope with our ...

AminoA+ Update and Autumn Recommendations 2016
AminoA+ Update With harvest 2016 coming to a close and also the first year of our commercial sales of AminoA+ we thought we should review the results and also make some recommendations based on this years’ experience. Yields OSR and Winter Barley yields were reportedly generally 30% down on 2015 levels this is undoubtedly a results of lack of sunlight in the early summer. (Two ...

Growth and yield response of rice varieties to foliar application of Boron | JBES 2020 @environmentalxpart
Abstract A field experiment was conducted during the Kharif season of 2018-19 at Rice Research Station Bahawalnagar on the calcareous sandy loam soil to assess the effect of foliar application of boron on growth & yield components of rice varieties (Kissan & Punjab Basmati 2016).The foliar application of boron aqueous solution was used as treatments comprised of control, 0.5kg/ha, ...

Variable Rate Seeding with Drone Imagery
Getting a good crop canopy across the entire field is important for better crop quality and higher yield. One way of achieving this is by varying the amount of seeds. In recent years more and more farmers have started using variable-rate technology. By coupling the tractor’s GPS equipment with the seed drill, the seed amount can be varied across the field based on a predetermined plan. The ...
