Who Am I?

Peach leaf curl is caused by the fungus Taphrina deformans and is a common fungal disease that infects several plant species. Though, peaches are the most susceptible crop and hence the name.

The pathogen can be found on the host’s branches, buds, and bark. It can survive harsh weather conditions, withstanding summer’s high temperatures and prolonged dryness.

At the end of a dormancy period, the fungus activity extends due to significant wetting events. As the weather changes and the flower buds swell, water splashes from irrigation or rain and causes fungus spores to reach the buds. That’s where the infection takes place, despite the fact that no green tissue is present.

After the pathogen enters the host, it stimulates cells, which leads to abnormal growth. Visual symptoms first appear as reddish areas on newly emerged leaves. With time, swelling and leaf distortion cause fungus spores to break outside, release into the air, and infect new tissues.

As the disease progresses, leaves may fall and be replaced by a new set of healthier leaves if a period of low humidity is present during their development. The loss of leaves during springtime results in decreased fruit production, defoliation, and could expose branches to sunburn.

Control Measures

Tindakan pencegahan merupakan kontrol terhadap perkembangan hama dan penyakit. Pada umumnya 2 metode penyemprotan disesuaikan dengan fase pertumbuhan fisiologis tanaman. Perlakuan pertama dilakukan sebelum terjadinya perkembangan kuncup. Dan perawatan kedua dilakukan pada saat kuncup mulai berkembang.

Produk yang digunakan oleh satu atau sebagian dari dunia adalah mengandung bahan aktif sebagai berikut:

Produk jenis fungisida adalah dithianon, captan, copper dan bordeaux mixture.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
