This week’s garden mission – eliminate squash bug eggs before they become squash bugs!
Scouting for pests in your garden on a regular basis is a MUST. Scouting alerts you to problems before they get out of hand. This time of the year as you scout among your squash plants you may see squash bug eggs. They are not too hard to spot and should be in a cluster:
If you find an egg cluster congratulate yourself because you can now stop this pest cycle. There are several ways to do this. You could remove this leaf. Or, flick the eggs off the leaf with your fingernail but you run the risk of just moving a viable egg that could eventually become a squash bug. There is an easy way to get rid of these eggs and keep the squash leaf intact.
First, cut a short length of tape. Clear packing tape seems to work very well:
Next, press the tape on top of the eggs. Press firmly and move the tape around a bit. The eggs stick to the tape:
Finally, remove the tape and fold it. Crush the eggs within the folded tape and your potential pest problem is removed. Notice the squash leaf is intact.
If you miss scouting and missed finding the squash eggs, the eggs hatch and these squash nymphs become squash bugs:
During periods of hot and dry weather, certain modifications to your lawn maintenance practices will help to carry your turfgrass through periods of inadequate rainfall and reduce losses. The height of the warm-season turfgrass growing season spans May through August. Given average conditions (regular rainfall and moderate temperatures), bermudagrass, zoysiagrass, St. Augustinegrass, centipedegrass, and other warm-season species respond quickly to cultural and maintenance practices such as mowing, fertilizing, aerating, topdressing, and weed management. However, the summer of 2016 has delivered hot and dry weather with less than normal rainfall. With August approaching, now is the time to fine tune your turf management program to salvage an acceptable appearance while minimizing growth until environmental factors improve.
The first order of business is to recognize moisture stress in turfgrasses in the early stages. Look for areas with a dull bluish-gray cast. Additionally, take note of footprints and tire tracks in the turf that do not seem to rebound.
Dr. Clint Waltz, UGA Extension Turfgrass Specialist, suggests these tips for managing turfgrass during drought periods:
Raise the cutting height within the recommended mowing range
Reduce fertilizer applications until conditions improve
Modify herbicide programs during high temperatures and moisture stress
Water deeply & Infrequently
Use water conserving and drought tolerant turfgrasses
Raise the Cutting Height
Turfgrass stress can be reduced by using a sharp mower blade and raising the cutting height by 1/2″ or to the tallest allowable height of the recommended mowing range during drought. A clean cut also reduces moisture loss through wounds and minimizes entry points for disease. Taller shoots promote deeper roots and a dense canopy can help to reduce ground surface temperatures and conserve moisture. Grasscycling (mulching clippings versus bagging) can also help to conserve moisture.
Reduce Nitrogen Applications
Plant growth requires water. Without water, the benefits of nitrogen are not optimized and you may be wasting product. Promoting heavy top growth amidst drought conditions increases water demand. Reduce rates or postpone fertilizer applications until environmental conditions improve to fully realize the benefits of fertilizer while saving water and reducing turfgrass stress.
Modify Herbicide Programs During High Temperatures and Drought
Many herbicides act upon plant growth processes and can be less effective during periods of drought when weeds are not actively growing. In addition, certain herbicides may cause damage to drought-stressed turf or non-target landscape plants due to volatilization and drift during high temperatures. Review your pesticide labels for specific information regarding temperature requirements, watering requirements, and proper application.
Water Deeply and Infrequently
The optimum watering schedule can be roughly determined by observing the number of days that pass between signs of moisture stress. Apply sufficient water to saturate the root zone to a depth of 6-8 inches. Clay soils and sloped areas may require staggered watering intervals to allow time for water infiltration between cycles and prevent runoff. Irrigating in early morning conserves water by reducing evaporation and drift. A good practice is to align watering schedules with drought management rules so that in the event of a declared drought, the appropriate watering program is already in place. As of July 26, 2016 there are no official declarations of drought by state or local authorities in Georgia and responsible landscape and lawn watering may take place between the hours of 4:00pm and 10:00am in accordance with the Georgia Water Stewardship Act of 2010. In the event that water resources require a drought response level 2, watering programs would need to be adjusted for the odd-even schedule by address.
Use Water Conserving and Drought Tolerant Turfgrass Cultivars
The University of Georgia Turfgrass breeding programs continue to make excellent strides in developing improved cultivars with low water use and high drought tolerance. For new installations or where turfgrass replacement is needed, look for improved certified cultivars such as TifTuf bermuda. Visit www.GeorgiaTurf.com for more information on selecting turfgrasses.
