  • Weakens plants, reducing fruit set.
Favorable Conditions for Early Blight
  • Temperatures between 15 to 27°C.
  • High humidity (>90%) and rainy weather.
  • Weak plants from June-July sowing are more susceptible.
Management of Early Blight
  • Use pathogen-free seeds and remove infected debris.
  • Water in the morning to minimize leaf wetness.
  • Implement crop rotation with non-Solanaceous crops.
Late Blight Overview
  • Caused by Phytophthora infestans.
  • Can infect leaves, stems, and fruits rapidly.
  • Historically linked to the Irish potato famine.
Symptoms of Late Blight
  • Dark brown blotches on leaves with green-gray edges.
  • Fruits develop dark, mushy spots.
  • High humidity leads to white fungal growth.
Favorable Conditions for Late Blight
  • High humidity (>90%) and low temperatures (10-25°C).
  • Cloudy weather with rainfall enhances spread.

Types of Tomato Products
  • Tomato Juice
  • Tomato Puree
  • Tomato Paste
  • Tomato Ketchup/Sauce
  • Dried Tomato Slices
  • Tomato Powder
  • Canned Tomatoes
Manufacturing Process of Tomato Juice
  • Tomatoes are washed to remove dirt and microbes.
  • Trimming and sizing reduce waste before juice extraction.
  • Extraction can be done via hot or cold pulping methods.
Hot Pulping Method
  • Crushed tomatoes are boiled to facilitate pulping.
  • Temperature reaches 82ºC to inactivate enzymes.
  • Results in viscous, deep red juice with longer shelf life.
Cold Pulping Method
  • Tomatoes are crushed at temperatures below 66°C.
  • Juice quality is inferior in flavor and nutrients.
  • Requires higher pressure, leading to lower yields.
Tomato Juice Production Steps
  1. Washing
  2. Cutting
  3. Pre-heating (60°C)
  4. Concentration (10-12°Brix)
  5. Filling
  6. Juice Extraction
  7. Pasteurization (100°C for 7 min)
Manufacturing Tomato Puree and Paste
  • Pulp is concentrated to produce puree (9-12% solids).
  • Tomato paste contains at least 25% tomato solids.
  • Further concentration yields heavy tomato puree.
Tomato Ketchup Production
  • Ketchup is made from concentrated tomato paste with added spices.
  • Ideal concentration is 28-30% total solids.
