Pests and diseases STRAWBERRIES
Pest
Aphids (Chaetosiphon fragaefolii)
Lice yellow-reddish yellow, small (1-2 mm), live clustered at the lower surface of leaves. Symptoms: shoots / leaves wrinkled, curled, formation of flower / fruit inhibited. Control: Insecticide Fastac 15 EC and Confidor 200 LC. Mites (Tetranychus sp., And Tarsonemus sp.) Mites are very small, oval-shaped females, males and triangular shaped somewhat reddish eggs. Symptoms: leaves mottled yellow to brown, curly, dry and fall. Control: Insecticide-EC Committee of 570, Mitac 200 EC or 18 EC Agrimec. Flower weevil (Anthonomus rubi), root weevil (Otiorhynchus rugosostriatus) and stem weevil (O. sulcatus). Symptoms: digerek the plants contained flour.

Control: Insecticide Decis 2.5 EC, 400 EC or Curacron Perfekthion 500 EC on the eve of the flowering phase. Mite White (Pseudococcus sp.) Symptoms: the plants are covered with a white tick will be abnormal. Control: Insecticide Chemical Perfekthion 400 EC or Decis 2.5 EC. Nematode (Aphelenchoides fragariae or A. ritzemabosi) Living at the base of the stem and even shoots of plants.
Symptoms: stunted growth of plants, the petiole thin and less hairy. Control: with nematisida Trimaton U.S. 370, Rugby 10 G or 10 G. Nemacur
Disease
Gray mold (Botrytis cinerea) Symptoms: the fruit brown rot and then dried. Control: the fungicide Benlate or Grosid 50 SD. Ripe fruit rot (Colletotrichum fragariae Brooks) Symptoms: bah-basahan kebasah cook a light brown and the fruit filled with pink spore masses. Control: with copper fungicide such as Kocide made active U.S. 80, Funguran 82 WP, Cupravit OB 21. Rizopus rot (Rhizopus stolonifer).

Symptoms:
rotten fruit, watery, light brown and when pressed will issue a turbid fluid; in storage, the fruit will be infected with fungal mycelium covered in white and black spores. Control: discard diseased fruit, good post harvest and cultivation with plastic mulch. Red core (Phytophthora fragariae Hickman) Symptoms: The fungus attacks the roots so the plants grow stunted, the leaves are not fresh, sometimes withering, especially during the day. Powdery mildew (Uncinula necator or mascularis Sphaetotheca). Symptoms: the affected areas, especially the leaves, covered with a thin layer of powdery white, flowers will wither and fall. Control: the fungicide Benlate or Rubigan 120 EC. Leaf footed (Diplocarpon earliana or Marssonina fragariae) Symptoms: Leaves mottled ovoid to irregularly angular, dark purple. Chemical control with fungicide Dithane M-45 or Antracol 70 WP. Leaf spot

Cause:
Ramularia tulasnii or Mycosphaerella fragariae, Symptoms: small purple spots on the leaves. Center brown spots that will turn out to be white; Pestalotiopsis disseminated, Symptoms: round spots on the leaves. Center FUA brown spots surrounded by a reddish brown edges or yellowish, leaves easily fall;
Rhizoctonia solani, Symptoms: large black-brown spots on the leaves. Chemical control with copper fungicide active ingredients such as Funguran 82 WP, 77 WP or Kocide Cupravit OB 21.

Late blight (Phomopsis obscurans).Symptoms: bula stain gray surrounded by red-purple color, and stains form a wound like a V. Control: with Dithane M-45, Antracol or Daconil 70 WP 75 WP. Vertisillium wilt (Verticillium dahliae) Symptoms: The infected leaves yellowish to brown, wilted and dead plants.Control: through gas fumigation with Basamid-G.
Virus
Transmitted by insects aphids or mites. Symptoms: leaf color changes from green to yellow (khlorosis) along the veins or spotted (motle), leaves become wrinkled, stiff, stunted plants. Control: use of virus-free seed, destroying infected plants, spraying pesticides to control insect carriers of the virus. Prevention of pests and diseases can generally be done by keeping the garden / plants, plant simultaneously (to break the life cycle), growing healthy seedlings, thus giving the recommended fertilizer to grow healthy plants, crop rotation with crops do not family Rosaceae and prune the plant / revoke diseased. Cultivate strawberries with plastic mulch will also suppress the growth of pests / diseases. Especially for diseases, improvement of drainage usually can reduce attacks.
