Bees gone for a break too?
Here's the whole article.
The other was a possible fabrication. Farmers ask why GM crops perform worse in drought Farmers ask why GM crops perform worse in drought The Network of Concerned Farmers, an alliance of farmers with concerns regarding genetically modified crops, are calling for research to determine why GM crops perform worse during droughts. "There is more than enough evidence to reveal that GM crops perform worse than non-GM crops during drought conditions but this vital information is being ignored," said Julie Newman, National Spokesperson for the Network of Concerned Farmers. "Farmers worldwide have complained that GM crops perform worse than non-GM crops during drought including GM cotton in India and Indonesia, GM soy in the United States and Brazil and GM canola in Canada. Australian farmers have even stated that they use an additional irrigation for GM cotton so it appears there is evidence that GM crops need more water," she said. "Our Federal Minister for Agriculture is making outrageous statements wanting states to ignore economic risk and claiming we need GM crops to counter drought when reality shows GM crops perform worse in drought. Australia is known for adverse conditions and may be totally unsuitable for GM crops but nobody seems to care about this vital detail." There has recently been a significant drop in soybean production due to the drought in Brazil. The president of the Rio Grande do Sul seed association sites 25% higher crop losses in GE soy crops as compared with conventional ones. Brazil's agricultural department estimates that yields are down 72% in Rio Grande do Sul which is the biggest adopter of Monsanto's Roundup Ready GM technology. "Many Brazilian farmers who use Round-Up Ready soy will be thinking twice about it next year," said Etienne Vernet, South American Research Director of the Polaris Institute. Governor of Mato Grosso (25% of national soy production) has publicly stated that he will not plant genetically modified soy next year. Monsanto and Bayer Cropscience withdrew from the proposed independent trials in NSW in 2004 with Bayer Cropscience stating a concern for dry conditions as a reason. Requests for further independent testing has been denied but Bayer Cropscience has been growing canola under irrigation for export to Canada under special state exemption orders. "Farmers need trials to compare GM performance during adverse conditions and scientists need to investigate this further. Farmers have had enough of the bulldust, we need facts." Non-GM drought tolerant varieties of wheat are being grown in Australia. Mrs Newman claims there are far better alternatives in non-GM biotechnology but some scientists are more interested in attracting corporate investment so are misleading farmers to believe all biotechnology is GM. Contact: Julie Newman 08 98711562 or 08 98711644 or 0427 711644 At least thirty companies developing GM crops have observed DNA instability with up to 5% disruption of overall gene expression which increased or decreased the protein producing outputs of other genes. Does recombinant DNA techniques destabilise the metabolism of the plant resulting in the need for more nutrients? Does the inserted gene and perhaps other insertion-caused “hotspots” remain hyperactive and deplete the nutrients of the plant? |

Bees gone for a break too?
I was in Tassie, having been made aware of the problem of bees getting to
"bee" scarce. Saw their imported from New Zealand bumble bees foraging in my sisters garden. I'm not sure what damage these are doing there, but feel their leatherwood honey producers are very concerned. Does anyone know what would happen on the mainland if they make their way here? It seems that the accidental importation (from NZ) may create a superior to local bee, as their pollination is far more productive from what I've read, as is their method of attack, when disturbed, as they can sting many times....

The world will not starve without bees but life would be more difficult and certainly more boring. While the major crops that provide callories (grains) mostly don't need bees many minor crops do, including many fruits and vegetables.

I have seen my tomatoes turn up their toes become very straggly and get sick
like I described. If I knew the cause I would not be trying to prevent everything..The Dusting powder is recommended to be applied every 5 to 10 days and is a multiple disease preventative..Unfortunately this had some disastrous effects with the bees. I think some of the survived and I saw a couple in my garden again. The problem is they're few and far between. Do bees pollinate tomatoes or are they self pollinating?

Do bees pollinate tomatoes or are they self pollinating? Depends on which bees you mean. Honeybees do not pollinate tomatoes, but many native bees do (and if you're in Tasmania bumblebees will also pollinate them). Tomatoes require a special kind of pollination called buzz pollination, which honeybees cannot do. I understand that tomatoes can be effectively wind pollinated, but don't know much about it.

The only answer , as I'm not a scientist or expert on diseases is "all of
em" as its a multi purpose dust. I don't know what causes the plants to get sick. When I get my Diploma of Plant diseases, I could answer you.. As it is, I'm as much in the dark as you are regarding the problems I have had in the past. I will take pictures if I see the diseases, and put them on the web, then some one may know. The problem occurs as described previously.. It could be mildew /fungal problems or a virus disease transmitted by thrips. It seem to happen later on into the season and they blacken and dry out. High humidity, lack of air movement seems to hasten the problem and tomatoes are not very productive after that. BTW, I am not as careful lwithe watering the plant as I should be as the leaves often get wet and make contact with the soil... PS I wish I did have that diploma.... but that all I can give you.

Pick off lower leaves, the ones most likely to pick up fungal spores from the soil. Grow on stakes, and thin foliage if it looks like bunching, so air circulates better. There is opportunity to experiment with companion planting (basil). But my primary suggestion for the home gardener: grow cherry tomatoes, and get them in early in the season. Their fruit sets and ripens so quickly that many diseases don't get a foothold, and they seem to be overlooked by both fruitfly and, I've found, thieving birds. Besides, each cherry tomato is a small morsel, so pop it into your mouth and eat it whole, no need to inspect for fly larvae!

You are right, I've been gardeniung for years, and I am of the conclusion
that the type of Tomatoes is more important than disease prevention. I'm always trying to improve my knowledge on this though, as I feel these plants shouldnt have to be molly-coddled. The plants I am growing at the moment appear to do OK at present, and are the disease resistant Appolo improved, grafted with the cherry tomato rootstock no doubt. They are holding out at ther moment, but when Italian growers cannot even get good results, I have to scratch my head to. The bees are returning, so things may not have bee(n) so bad as I first thought. Lavender does help.. "John Savage" wrote in message ...
