New cereal seed pickle now fully registered

“Ambush” is presentlybeing developed in New Zealand by ICI Tasman Ltd for a wide range of insect and crop uses. It has shown remarkable, effectiveness against codling moth in pipfruit, leaf roller in citrus, kiwifruit, pipfruit, stone fruit and berry fruits, tomato fruit worm in tomatoes, corn earworm in sweetcorn and maize, white butterfly and diamond-back moth in vegetable and forage brassicas, whitefly in glasshouse crops, . grass grub adult beetles in pasture and many other insect pests.

Bayer AG, after a number of years research overseas and four years of evaluation in New Zealand have recently received full registration for a new cereal seed pickle called Bavtan Fl 7.

Crop surveys have indicated that the level of soil and seed-borne diseases has increased since the organo mercurial seed pickles were last used in 1973.

From numerous trials up and down the country, it has been found that the systemic seed pickle controls not only seed-borne diseases but also the main foliar diseases of powdery mildew and rust. Over the last two seasons in barley trials sown during October Baytan Fl" out-yielded standard seed treatments by just over 9 per cent while in those sown during November when rust infection was high the average yield increases were over 30 per cent, according to the firm. Results .to date prove

the yield benefit which can be gained by using the seed pickle on barley seed not only sown at the usual time, but also opens new potential for the crop to be grown in November when often rust infection reduces the yield potential greatly.

In autumn and spring sown wheat average yield increases from the use of Baytan Fl 7 over standard seed pickles have been just over 5 per cent in crops with low disease levels, while in crops heavily infected with rust the increase has been just on 18 per cent, the company says. The results have certainly been outstanding, however, the yield response gained from the use of the seed pickle is largely dependent on the diseases infecting the crop. Therefore the greater the disease the greater the yield response.

The distributors of Baytan Fl 7 in New Zealand —Henry H. York and Co.,

Ltd., — advise that this new seed pickle will be available from grain and seed merchants for the 1979 spring sown crops. The question asked is

what will all this cost? The manufacturer claims a 1 per cent increase in yield in the average crop will cover the extra cost of treatment.
