&#34;Red rust of tea&#34; is caused by parasitic:-a)Algaeb)Fungic)Bacteriad)BryophytaCorrect answer is option 'A'. Can you explain this answer?

Answer

Parasitic green alga which causes the disease 'red rust of tea' in tea plants and 'leaf spot disease of guava' in gauava plant. It also causes leaf spot diseases in other plants like mango, magnolia and coffee.

Answer

'Red rust' caused by Cephaleuros parasiticus Karst is the most important and lone algal disease of tea.

Answer

The red rust if tea( Camellia sinensis) is caused by an algae if genus cephaleuros. It causes orange velvety patches in the plant.

Answer

Red rust of tea is caused by parasitic algae. Algae are photosynthetic organisms that can be found in various habitats, including aquatic environments. They are characterized by their ability to produce their own food through photosynthesis, using sunlight, carbon dioxide, and water.

Explanation:

Causes of Red Rust of Tea:

1. Parasitic Algae:
Red rust of tea is caused by parasitic algae, specifically a species called Cephaleuros virescens. This parasitic algae belongs to the family Trentepohliaceae. It infects tea plants and forms reddish-brown, powdery rust-like patches on the leaves and stems.

2. Ideal Conditions:
The growth and development of parasitic algae like Cephaleuros virescens are favored by specific environmental conditions. These conditions include high humidity, warm temperatures, and the presence of moisture on the tea plants. Tea plantations in tropical and subtropical regions are particularly susceptible to red rust.

Effects of Red Rust of Tea:

1. Reduced Photosynthesis:
When tea plants are infected with red rust, the parasitic algae cover the leaf surface and inhibit the plant's ability to carry out photosynthesis effectively. This results in reduced energy production and can lead to stunted growth and decreased yield.

2. Weakening of the Plant:
As the parasitic algae continue to spread and grow, they can cause damage to the tea plant's tissues, weakening its structure and making it more susceptible to other diseases and pests. This can further reduce the overall health and productivity of the tea plantation.

Control Measures:

1. Cultural Practices:
Proper cultural practices can help minimize the incidence and severity of red rust in tea plantations. These practices include regular pruning to improve air circulation, reducing the density of the tea bushes, and maintaining proper plant nutrition and hygiene.

2. Chemical Control:
Fungicides and algaecides can be used to control red rust. These chemicals are applied to the tea plants at specific intervals to prevent the growth and spread of the parasitic algae. It is important to follow the recommended dosage and application instructions to ensure effective control without causing harm to the tea plants or the environment.

In conclusion, red rust of tea is caused by parasitic algae, specifically Cephaleuros virescens. This parasitic algae infects tea plants, leading to the formation of reddish-brown rust-like patches. It affects the tea plant's photosynthetic capacity, weakens its structure, and reduces overall productivity. Proper cultural practices and chemical control measures can be implemented to manage and control red rust in tea plantations.
