Seed Treatment – An Investment that Pays H
eavy precipitation last year in most parts of the prairies has set the stage this year for poor seed quality and high disease pressure. And, of course, there is no way of predicting what this year will bring in terms of disease pressure. Disease forecasts for 2011 predict that overwintering inoculum levels will be high for seed and soil-borne diseases such as tan spot, septoria and fusarium head blight on wheat, net blotch and scald on barley, ascochyta blight on chickpeas and peas and white mold on canola and pulses. Cool spring conditions could delay germination and excessive moisture in April will increase seedling disease pressure from seed decay, leaf spots and blight. More than ever, getting the seed out of the ground and well established is critical. There are several practices growers should respect: follow the recommended crop rotations, use resistant varieties whenever possible, scout fields and protect seed from disease with a seed treatment. Today’s seed treatments have evolved significantly over the past several years. Consider Raxil® MD, a combination of two highly effective systemic fungicides, tebuconazole and metalaxyl. The water-based, ready-to-use formulation is designed for both commercial and on-farm treating. Micro-dispersion technology ensures that the seed is uniformly covered, which is essential for effective control. And with the introduction of Raxil WW, growers can protect against disease and wireworm damage.
Protect your seed, right from the start Cold soil For reduced tillage growers seeding into cold soil, the soil temperature can delay crop establishment and opens the door to infection from seed- and soil-borne diseases. Seed treatment protects the seed during this time until the soil temperatures increase.

Warm soil For soil that is warm, growers need to be aware that Fusarium garminearum, the pathogen that causes fusarium head blight flourishes causing seed blight, and root rot. Seed treatment will protect against Fusarium garminearum ensuring the seed germinates and gets out of the ground.
Seed-borne disease For seed that hasn’t been tested for seed-borne diseases, it is wise to use a seed treatment to prevent fusarium and smuts from developing. If you’ve purchased certified seed, the tag should indicate whether any diseased kernels were found along with the type of disease.
Insect pressure If there has been insect pressure historically or at seeding, consider applying a seed treatment like Raxil WW that contains both a fungicide and an insecticide. This will prevent damage to the plant from emergence until the crop is established.
Crop rotation The risk with continuous cropping is the build-up of disease inoculum in the soil. Seed treatment can help minimize potential losses from these soil-borne diseases. It is advisable to follow strategic crop rotation and use a good quality seed treatment. Not only will the current crop be protected, the build-up of disease inoculum can be avoided in the future. Whether growing conditions are ideal or not, using a seed treatment pays off in the long run, helping to establish the crop and deliver higher yields and better quality this season and keep soil healthy for the next growing season.

The Toughest Thing in Pink W
hen it comes to choosing a cereal seed treatment, you want one that comes out swinging against disease. And that’s what Raxil cereal seed treatment delivers. Registered on wheat, barley and oats, Raxil provides a cost-effective way to knock out seed- and soil-borne diseases. Along with its easy-to-apply water-based formulation, the combination of the systemic fungicides tebuconazole and metalaxyl in Raxil deliver powerful, effective control of all major seed- and soilborne diseases. These diseases won’t know what hit them. Because Raxil has extremely low viscosity, it can be applied in cooler temperatures without becoming too thick. In fact, viscosity won’t increase dramatically until it actually freezes (-10°C). Two serious contenders in the early season are fusarium and smuts disease complex. Raxil is a valuable tool to limit the impact of fusarium. Along with head blight, fusarium causes seed rot, seedling blight and root rot, seriously harming crop establishment and causing yield losses. Cereals treated with Raxil outperformed the untreated check by an astounding 29 per cent and surpassed the competitor product by 4 per cent. Left unchecked, true loose smut can knock barley yields back by up to 20 per cent. The systemic activity in Raxil protects barley from the minute the seed hits the ground, helping crops get off to a healthy start.

Slams Wireworms Wireworms are increasingly becoming a problem in cereal crops all across western Canada. Wireworms cause damage by hollowing out the seeds before germination and feeding at the base of seedlings. Injured plants may wilt and die, resulting in thin plant stands. With heavy infestations, bare spots may appear in the field and reseeding may be required. Raxil WW is a co-pack of Raxil MD and Stress Shield™, an insecticide designed to put the smack down on the dreaded wireworm. Now you can get the benefits of Raxil MD, along with the effective wireworm protection of Stress Shield, to provide the toughest seedling protection. Imidacloprid, the active ingredient in Stress Shield, works through both ingestion and contact properties. Wireworms that come in contact or feed on Stress Shield protected seeds and seedlings enter into a prolonged coma-like state. Feeding is halted and the crop continues to grow. When the wireworms are ready to feed again, the crop is fully grown and is no longer susceptible to losses from wireworm feeding. CT

ith so much time, energy and money invested in pulse and soybean crops, there’s no better way to protect that investment than by treating seed with Trilex® AL. Trilex AL’s combination of two powerful active ingredients – trifloxystrobin and metalaxyl – provide the best protection from diseases caused by rhizoctonia, fusarium, pythium, botrytis, ascochyta and phomopsis on labeled crops. Check out these results. In Bayer CropScience trials conducted in western Canada, Trilex AL outperformed the major pulse seed treatment competitors and performed way ahead of untreated checks for control of rhizoctonia and fusarium in pulses and botrytis in lentils. In the lentil trials specifically, plant stand was 136.7 per cent greater than check and yielded 122 per cent better.
In field peas, the stand topped the check by 133 per cent and outyielded the check by 129 per cent. In chickpeas, plant stand was an impressive 406 per cent of the check and yielded 301 per cent of the check. In all these crops, Trilex AL outperformed competitors. In dry beans, which are very susceptible to disease, the plants treated with Trilex AL produced plant stands 1,432 percent greater and yields 126 per cent greater than the checks – equal with competitors.
Inoculant compatibility Not only is Trilex AL one of the best seed treatments available for pulses and soybeans, it has excellent compatibility with pulse inoculants. Trilex AL has been extensively tested by inoculant companies and has proven to have one of the highest compatibilities between fungicidal seed treatments and rhizobium-based inoculants. Increased compatibility means Trilex AL takes care of the disease, gets your plant established and clears the way for the inoculants to supercharge nodulation. CT
