Insects, calcium can cause several turf problems

Mole crickets can do a tremendous amount of damage to lawns and golf courses. These destructive insects hatch around the third week of June, so be prepared. One or two applications of Orthene, Dursban or Oftanol should control the crickets.
Chiggers, also known as red bugs, can be a problem in lawns. These insects usually attach themselves to humans in areas where clothing fits snugly, such as waist bands. Intense scratching results from chigger bites.
Check with a local pharmacist about soothing ointments for chigger bites.
Mowing lawns and turf infested with chiggers will reduce their numbers. Sevin, Malathion and Pyrethrin applications offer good control.
Heavy rain has brought out millipedes and centipedes around houses and lawns. An application of Sevin in a band within 12 inches of the house and patio walls will control these pests. Several applications at seven-day intervals may be necessary.
The Influence of Calcium
Calcium is essential for healthy growth and high yield in vegetable plants.
It combines with toxic acids in the plant making them harmless. It also helps the plant absorb nutrients and overcome the effects of a nutrient imbalance.
Deficiencies of calcium in plant tissue cause several common problems.
These problems are not pathogenic diseases, but they can be mistaken for such.
Some of the conditions include tip burn in cabbage and lettuce; blossom end rot in tomatoes, watermelons and peppers; cavity spot in carrots; and brown heart of escarole.
Calcium deficiency mainly occurs in vegetables planted in acid soils. It is more probable in soils with high potassium or little moisture.
Home gardeners and vegetable producers can avoid calcium deficiency by maintaining a high enough pH with limestone, avoiding over fertilization with nitrogen and sidedressing with calcium nitrate instead of ammonium nitrate.
