Plant Seed Germination
Arizona Veg IPM: Bagrada bug, soil solarization, and weed seed germination
, Was a major problem in desert cole crops last fall. Widespread infestations were reported throughout the desert growing area in September and October where stand losses and yield/quality reductions to broccoli, cauliflower, cabbage, and other Brassica crops were considered economically significant in some growing areas.In an attempt to document the impact of these outbreaks on desert production, a survey of pest control advisers (PCAs) from Yuma and the Imperial Valley was recently conducted to estimate the severity of Bagrada bug infestations on direct-seeded and transplanted cole crops during 2010.
A summary of the survey results can be found at this link: Bagrada Bug Survey 2010 .
In general, a large percentage (98.6 percent) of direct-seed cole crop acreage (e.g., broccoli) was treated for Bagrada infestations with insecticides compared to transplanted cole crops (e.g., cauliflower) where 86.6 percent of the acreage was reported treated.
Similarly, estimates showed that direct-seeded cole crops sustained greater stand losses and plant injury from Bagrada feeding than transplanted crops. When combined, the average estimated stand loss and plant injury caused by Bagrada bug exceeded 15 percent and 10 percent in direct-seeded and transplanted crops, respectively.
PCAs also provided information on insecticides that provided effective control through chemigations and foliar sprays. In general, they reported that products that have contact activity (i.e., Pyrethroids, OP/Carbamates) appeared to provide the most effective control against Bagrada adults on direct-seeded and transplanted cole crops.
Overall, the results of the PCA survey are consistent with results obtained in research trials conducted at the Yuma Agricultural Center in Yuma last year.

Plant Seed Germination - News
Many variables impact the survival and germination of weed seeds which can differ from region to region. The latest Arizona Vegetable Integrated Pest Management Update from the University of Arizona (UA) Cooperative Extension in Yuma, Ariz. released
Older plants will sometimes reward you with a seed pod. Seeds resemble small, hollow toothpicks and are easy to germinate. These desert roses will grow to 6 inches tall in their first year. They will continue to grow 6 to 8 inches a year throughout
Good butterfly nectar plant. For best germination rate, seeds should be cold-stratified for 2-4 weeks prior to planting. Plant outdoors in an area of full sun to partial shade. Grows best in moist soil. PURPLE CONEFLOWER Perennial; Height: 2 to 3 feet;
Their seeds will scoop out easily from the interior chambers inside the fruit. To germinate tomato seeds next year, the gel coating must be removed. This can be flaked off when the seeds are well rinsed and completely dried on a cookie sheet or wax
(email reference) Keep in mind that the seeds you collect and the resulting seedlings will not be the same as the parent plant. To keep the same characteristics of the parent, you need to do asexual propagation. Germinating peony seeds (herbaceous or
How to Germinate Marijuana Seeds :: part 2 :: Quick and Easy ...
This is a series of videos that will teach you how to germinate marijuana seeds. alturl.com Germinating marijuana seeds is actually quite easy, and this video will teach you how to germinate marijuana seeds to grow marijuana plants by using damp paper towels/napkins. It is a fairly simple method of marijuana seed germination for growing marijuana plants. These videos were a big help to me when I was first learning how to grow marijuna and I hope that everyone else learns something from these videos on how to germinate marijuana seeds.
@22matt19 hmm… honestly don’t know, it really depends if it’s sprouted yet. If it’s green and has a nice stem then it should be fine, I’d look after it or put a through a towel over it if you planted it outside and it hasn’t sprouted yet. Actually I’d through a towel over it and stake it to the ground anyway just as a precaution, so it doesn’t freeze the water inside the seedling, causing it to snap.
Q&A :: what does it mean when a weed plant has the seed growing on top instead of from the root?
Q&A :: Many plant species exist as separate male- and female plants. How do they propagate from the seed?
