Simple Garden Pest Control

Friday, July 2nd, 2010

Pest control is one of the biggest issues for gardeners everywhere. Insects can kill a garden quickly, and ruin months of work and planning in a matter of days or weeks. Seeing a prized plant eaten by pests is a heartbreaking event, but it is one that can be kept away from with a little additional work on the part of gardeners. There are many solutions for pest predicaments, from using specific plants to utilizing chemical pesticides.

Identifying Garden Pest predicaments

One of the best ways to stop pest predicaments before they get out of hand is to learn the symptoms of various pests. Looking for the ordinary symptoms of various garden predicaments is a simple way to get pests under control.

Some ordinary symptoms of pest infestation include

  • Small holes in leaves
  • Yellow or brown leaf edges
  • Holes in the stems or petals of plants and flowers
  • Premature leaf loss

Look for the presence of insects like grasshoppers, whiteflies and aphids on plants to determine what type of pest is attacking the garden. Knowing what categories of pests are around can affect the most effective method of pest control.

There are many ways to control pests in a garden, and these can be tailored to solve a particular predicament. Focutilized and specific pest control practices are more surroundingsally friendly, cost-effective and require less labor over time.

Pest Control Services

Hiring a pest control service is a simple way to reduce the presence of garden pests. Pest control services spray pesticides over plants that help to kill eggs and mature insects, rigorously reducing insect populations very quickly. However, there are issues with pest control services that gardeners should admit as true that.

General chemical pest control kills all insects in a garden, including the beneficial ones like honeybees and butterflies, as well as the ladybugs that can help to eat aphids, a ordinary garden pest. Losing these beneficial insects can make a garden less healthy over time, and require more applications of chemicals.

Most chemical pesticides are heavily reliant on fossil fuels for their creation, transportation and application, as well. Oil dependency is surroundingsally risky, and applying these chemicals to a garden can increase both global warming and surroundingsal pollution.

Even though pest control services provide a short-term solution to a serious pest predicament, there are better ways to combat pests in the long term.

Biological Pest Control

Biological pest control is a type of pest control that utilizes organic means to combat infestations of insects. One of the most ordinary categories of biological pest control is the utilize of ladybugs to rigorously reduce aphid populations. Ladybug populations are low due to invasive species, which means that aphid populations can rise quickly.

Many university extension and gardening centers provide biological pest control services. A group of ladybugs released into a garden infested with aphids can eat aphids quickly and effectively, while simultaneously advertising the local population of true ladybugs.

This type of biological pest control can be very effective in controlling garden pests, greenhoutilize pest predicaments and many other areas of gardening.

Planning a Garden for Pest Control

There are a number of ways to plan a garden to more effectively resist pest predicaments. Utilize local, native plants in a garden –these plants have evolved to survive in the area, and are more likely to be pest-resistant. additionally, they require less maintenance, watering and fertilizer.

Plan a garden that utilizes plants that repel pests, such as Artemisia and basil. Chives repel the Japanese beetles that can kill many garden plants, and catnip repels a number of other pest insects. Putting these plants throughout a garden can help keep away insects that would feed on and kill other plants.

utilize plants that attract beneficial predatory insects, as well. Plants like dill attract predatory wasps that reduce pest populations, and attract tomato hornworms that can kill tomato plants. Putting dill at a distance from tomato plants can help protect them. Hyssop is a good plant for attracting beneficial honeybees to a garden, which can then pollinate many flowers.

Pest control is a serious challenge for gardeners. Keeping plants healthy and free of pest insects can take up a great deal of time, effort and money. However, there are simple, easy methods of solving pest predicaments without resorting to chemical pest control. additionally, many of these organic methods can help make a garden even more beautiful.

White Mold of potato

Tuesday, April 27th, 2010

White mold of potato( also called sclerotinia stem rot) is caused by the fungus Sclerotinia sclerotiorum (Lib.) de Bary.

The disease well develop in moist conditions and is especially common in fields with overhead-irrigation such as by means of a center pivot. Agricultural practices that promote extensive canopy growth and keep relative humidity and free moisture in the crop canopy for extended periods of time and reduce wind movement, favor disease development.

Symptoms of white mold

White mold symptoms first appear as water soaked lesions 14 to 20 days following row closure. Lesions usually first appear in the intersections between the stem and branches, or on branches and stems in contact with the soil. These become quickly covered with a white cottony growth that can spread rapidly to nearby stems and leaves if moisture is present for several hours. As lesions expand they can girdle stems causing foliage to wilt. White mold is also often accompanied by bacterial stem rot, especially under wet conditions.

When conditions become dry, lesions dry out and turn beige, tan or bleached white in color and papery in appearance. As infected tissue decays, hard irregularly shaped resting structures called sclerotia form on the inside and outside of decaying tissue. No stem rot symptoms are observed on below-ground tissues( i.e. roots, stolons or tubers).

Management of white mold disease

Effective management of white mold requires implementation of an integrated disease management approach. The disease can be controlled primarily through the use of cultural practices and foliar fungicides.

Good fertility management to prevent excessive canopy development will also suppress white mold. As such, cultivars that naturally produce thicker, dense canopies are at higher risk of white mold, than those that produce sparser canopies.

Use of the biological control agent Conithirium minitans, a parasite of S. sclerotiorum sclerotia, to reduce the sclerotia bank in the soil has yielded conflicting results between the regions where the experiments were conducted.

The most widely cultivated commercial growers of potato are equally susceptible to Sclerotinia stem rot. In the absence of resistant cultivars, chemical control with fungicides remains the most effective management tactic. Successful fungicide products include Iprodione (a.i. iprodione), Botran (a.i. dichloran), Omega (a.i. fluazinam), Quadris (a.i. azoxystrobin), Topsin (a.i. thiophanate-methyl) and Endura (a.i. boscalid).

The long-lived sclerotia can be killed by flooding for about 5 weeks. Rotations with nonsusceptible crops, including potato only every third year, along with removal and destruction of infected plants, help reduce this disease. Avoid
overhead irrigation.

Field, greenhouse and in-vitro experiments have shown that there are no significant differences in the effectivness of these compounds. Using of these fungicides at initial full bloom are effective in reducing the number of infected stems.
However, using of the same fungicides made at or prior to row closure following label recommendations were found to offer erratic protection at best.
