Golf courses go greener

Turfgrass managers have taken up the mantle of sustainability.  Over the past decade, a number of golf courses around the country have even started to "go organic"!

Some of the alternatives to synthetic pesticides proposed by one golf course site include:

1. Beneficial insects
2. Beneficial nematodes
3. Bt (Bacillus thuringiensis)
4. Compost
5. Corn gluten
6. Fish emulsion
7. Garlic oil/juice
8. Horticultural oils (vegetable-based instead of petrochemical based)
9. Kelp/seaweed extracts
10. Lemon & vinegar formulations
11. Lime
12. Beneficial microbes and microbial derivatives
13. Milky spore
14. Neem
15. 100% "organic" fertilizers
16. Pheromone lures
17. Pyrethrin/pyrethrum
18. Rock dust minerals
19. Biopesticides
20. Products on the national list of approved substances established under the Organic Foods Product Act of 1990
21. Products approved as organic by duly accredited certifying organizations such as the Northeast Organic Farming Association (NOFA) and the Organic Materials Review Institute (OMRI)

And some of the proposed prohibited substances include:

1. All synthetic chemical pesticides
2. Arsenic
3. Biosolids derived from sewage sludge or industrial waste (i.e. Milorganite)
4. Genetically modified products, ingredients, or seeds (endophytically enhanced seed and improved grass seed cultivars produced through conventional breeding programs are not GM and therefore are permitted.)
5. Piperonyl butoxide and other synthetic ingredients
6. Pyrethroids
7. Tobacco
8. Pesticides dispensed by automatic misting systems

Updated: Crop Protection Compendium

UW-Madison Libraries subscribe to the Crop Protection Compendium database from CABI, which is now available on their new interface in beta.

This online multi-media resource can be searched by keyword, or browsed by animals (arachnids, molluscs, nematodes, birds, mammals), bacteria, fungi, oomycetes, plants, protozoa, unknown aetiology, and viruses.  It includes:

* 2,800+ detailed data sheets on crops, crop pests, diseases, weeds, invasive plants, natural enemies, pesticides and biopesticides

* Information on an additional 27,000 species, including distribution maps

* 8,000+ pictures to allow for easy identification and teaching

* 200,000 article records from the CAB Abstracts database (updated weekly), including 6,500 full-text journal and conference articles

* 9,000+ term interactive glossary

New soybean pest: Trochanter mealybug

Infestations of the trochanter mealybug (Pseudococcus sorghiellus, in the Order Hemiptera, Suborder Homoptera, Superfamily Coccoidea and Family Pseudococcidae), an unarmored scale insect, were first identified in Midwestern soybean crops in 2008.  They can be found on the roots of soybeans that appear to be suffering from potassium deficiency (yellowing of the leaves).
