Healthy Water At Millets Farm

Healthy Water At Millets Farm: With two mature lakes covering roughly four acres and home to hundreds of fish, Millets Farm Fly Fishing Club takes its water quality incredibly seriously. So, it’s no surprise it’s turned to Otterbine to help achieve the best water quality possible.

Having installed an Otterbine Fractional aerator last year in one of its lakes and seen vast improvements, the club has now opted to install a second Otterbine aerator which is vital to keeps its waters and fish healthy. Head Squared Aquatics chief executive Giles Head, who recommended and installed the Otterbine aerators for the club, explains.

“In the lakes at Millets Farm there’s a high level of anaerobic digestion, whereby bacteria break down organic and biological waste into carbon dioxide, ammonia and methane and this severely reduces the dissolved oxygen in the water. Plus, the lakes were suffering from thermal stratification, which is where the temperature changes at different depths in the lake which trout in particular are very sensitive to. It’s therefore vital to maintain high levels of dissolved oxygen to ensure the waters stay healthy, an even temperature throughout and suitable for aquatic life.”

And never has this been more evident to Giles than when one of the Otterbine aerators was damaged by fishing wire and had to be removed.

“Within just four days the oxygen levels dropped dramatically. Luckily for the fishing club they were loaned a replacement motor unit by Otterbine’s distributor Reesink Turfcare, so they could get the oxygen levels back to where they needed to be while their aerator was being repaired. But it just goes to show how delicate the water balance is and how quickly it can be disrupted.”

And with the poor results the fishing club were seeing with its last aerators, Otterbine has brought a welcome change, says Giles: “The club’s old aerators were only resulting in dissolved oxygen levels of between four and six percent. With the Otterbine Fractional aerators in place, the lakes are up to saturation point, getting the full amount possible.

“That’s why I recommend Otterbine systems,” he says. “I’ve been in the industry for a long time and seen that for every pound spent on an aerator, you’ll get twice as much dissolved oxygen in the water from an Otterbine than anything else. Plus, the customer service from Otterbine and Reesink is second to none.”

With the larger of two lakes at the club now benefitting from two Otterbine aerators, there are plans to potentially install another two in the other lake. Although smaller and served by a spring, and therefore not suffering as much and requiring the same urgent attention as the larger lake, ensuring water quality is the best it can be is very important to the club.

Eric Evans, fishery manager at the club concludes: “After speaking to Giles about the issues we were having, he supplied and fitted an Otterbine aerator after only three days, and within the week dissolved oxygen levels had reached super saturation and completely transformed the lake.

“We are thrilled with the service from Head Squared Aquatic and Reesink Turfcare, particularly with their loan of a replacement unit while ours was damaged, and we thank them both for their continued support.”

BASF To Launch New Farm Rodenticide

BASF To Launch New Farm Rodenticide: BASF have announced the release of Storm® Ultra Secure, a brand-new rodenticide which will be available in August 2019. The product contains 25 parts per million (ppm) of the active substance flocoumafen and will be available in a variety of sizes to professional users* and farmers as well as the general public.

The preparation of crop stores to prevent infestations of rodents and other pests is crucial. Rodents consume and spoil stored produce, spread disease to humans and livestock, attack growing crops and damage buildings. Preparing storage facilities on farms requires planning and an integrated pest management approach. Buildings should be cleaned, tidied and thoroughly checked prior to being regularly baited. This will help remove rodents before harvest and continued baiting will prevent infestations during autumn and winter. It is therefore essential for farmers to find the right product that has high efficacy and palatability.

BASF To Launch New Farm Rodenticide

Sharon Hughes, Global Technical Marketing Manager, for BASF explains. “Since second generation rodenticides were released in the 1970s and 80s to combat rodent resistance to the early anticoagulants of the 1950s, a complacency about rodent control has developed. It is believed that all second-generation actives have a high rate of efficacy and that rodents have little to no resistance to them. However, this is not the case because rats have already shown resistance to difenacoum and bromadiolone.”

Resistance is only one factor in the efficacy of a rodenticide. Palatability is an equally important consideration. The strength of the active is irrelevant if the rodent is not attracted to eat the product. It is therefore important to have an active that rodents are not resistant to and a product that is highly palatable to ensure a sufficient quantity of the active is consumed.

In laboratory trials conducted by BASF, rats were offered the choice between a controlled nontoxic food source and Storm Ultra Secure. The results showed that some rats chose to consume high quantities of the product even when nontoxic food was available. Sharon explains “Palatability is measured by the amount of the rodenticide consumed divided by the amount of the controlled diet consumed. The standard for most block baits range between 0.5 and 1.5”.

In laboratory tests with Storm Ultra Secure, BASF recorded quantities as high as 11.3 being consumed by rats and even the lowest levels were at least 2. This shows that the rats were consuming at least twice the normal dosage, with many choosing to consume much higher quantities of the rodenticide than normal. This proven palatability demonstrates that the new 25ppm bait is more effective than many 50ppm baits currently on the market.

Sharon concludes, “It is clear that rodents will continue to adapt, but none have built a resistance or tolerance to the flocoumafen active in Storm. By making Storm Ultra Secure more palatable we have created a 25ppm product that farmers can use to effectively control rodents on their farm.”

Rodent activity should be monitored all year round and farmers should look for signs of rats and mice at least weekly especially before harvest.
