ALSTASAN SILVOX (Silver Hydrogen Peroxide based Biodegradable Agriculture Disinfectant) addresses the following areas of concern without causing harmful/toxic effects.

 

Method of application:

Regular treatment by Spray method:

A solution of the disinfectant is made and sprayed on the plants once in every 7-15 days helps in treating:

  • Anthracnose by Colletotrichum fragariae, C. gloeosporoides, C. acutatum accounts for:

Leaf spot: Round black-gray leaf lesions

Runners and petioles: Round dark brown-black lesions on stems, petioles, runners; reduced plant growth and wilting occurs

Crown rot: Young leaves start to wilt that spreads to the entire plant accounting for its death; when the stem is cut lengthwise red-brown streaks are visible

Bud rot: Rotten brown-black buds resulting in wilted plants followed by death

Flower blight: Dark lesions extending down the pedicle, that encircles the stem, accounting for defoliation; infection after pollination accounts for small, hard, misshaped fruits

Fruit rot: Light brown lesions on the ripened fruits which develop into black round lesions

 

  • Botrytis Blight, by Botrytis cinerea causes brown dying misshaped fruits, that expand on the patches with grey mycelial covering over the affected parts leading to dead mummified fruits
  • Diplocarpon earlianum causes Leaf Scorch identified by irregular purplish brown leaf patches that coalesce later leading to girdling and wilting causing death
  • Powdery Mildew by Spaerotheca macularis is seen on the leaf and fruit surfaces as a white velvety covering which expand deforming fruits.
  • Phomopsis obscurans produces round red purplish leaf lesions that expand with a grey center, known as Phomopsis Leaf Blight
  • Red stele, caused by Phytophthora fragariae account for reduced plant growth, with orange tinged withered leaves; the new leaves being smaller in size with little to no fruit production; the red root discolouration extends down the crown
  • Xanthomonas fragariae causes thin leaf spots seen as water soaked lesions on lower leaf surfaces that expand to form dark green to translucent thin spots merging to form reddish spots with a chlorotic halo

Regular treatment by Drip method:

The disinfectant is added to irrigation water and fed to the soil bed through drip line. It is advised to repeat this process once in every 15 days.

  • Anthracnose by Colletotrichum fragariae, C. gloeosporoides, C. acutatum accounts for:

Runners and petioles: Round dark brown-black lesions on stems, petioles, runners; reduced plant growth and wilting occurs

Crown rot: Young leaves start to wilt that spreads to the entire plant accounting for its death; when the stem is cut lengthwise red-brown streaks are visible

Bud rot: Rotten brown-black buds resulting in wilted plants followed by death

 

  • Botrytis Blight, by Botrytis cinerea causes brown dying misshaped fruits, that expand on the patches with grey mycelial covering over the affected parts leading to dead mummified fruits
  • Phomopsis obscurans produces round red purplish leaf lesions that expand with a grey center, known as Phomopsis Leaf Blight
