Фитофтора 2025: Срочная Защита Томатов и Огурцов от Болезней в Холодную и Влажную Погоду

The video opens with Ivan's Science addressing the urgent situation affecting crops in the western region due to cold rains and low temperatures around +10°C. This temperature is critical because:

"при +10 уже огурцы прекращают свой рост и начинается отмирание корневой системы"
(At +10°C, cucumbers stop growing and root systems begin to die off.) 0:09

This sets the stage for the vulnerability of plants to diseases, especially the onset of phytophthora (late blight) on potatoes, which has already been observed:

"Вчера ко мне приехало фото... я с удивлением обнаружил что это уже фитофтороз"
(Yesterday I received a photo... and was surprised to find it was already phytophthora.) 0:18

Key points:

• Cold, rainy weather is halting cucumber growth and damaging roots.
• Plants become highly susceptible to diseases under these conditions.
• Phytophthora has already appeared on potatoes, signaling imminent risk to tomatoes and cucumbers.
• Past experience shows early disease outbreaks can devastate crops before harvest.

Ivan stresses the critical need to act immediately to prevent the spread of phytophthora and other diseases like peronosporosis (downy mildew) which affected cucumbers last year:

"Если сейчас не предпринять мер то можно... лишиться и урожая томато в открытом грунте"
(If no measures are taken now, you can lose your tomato harvest in open ground.) 0:38

"перноспороз уже начал уничтожать огуречники"
(Downy mildew has already started destroying cucumber beds.) 0:47

He highlights that the current weather is extremely favorable for the development of the most dangerous diseases affecting onions, garlic, cucumbers, and tomatoes:

"Погода чрезвычайно благоприятная для развития самых опасных болезней"
(The weather is extremely favorable for the development of the most dangerous diseases.) 1:00

Key points:

• Immediate intervention is necessary to save tomatoes and cucumbers.
• Weather conditions promote rapid disease spread.
• Diseases include phytophthora on tomatoes and potatoes, peronosporosis on cucumbers, and fungal diseases on onions and garlic.
• Early symptoms are difficult to stop once visible, so prevention is better than cure.

Ivan recommends using ready-made biological protectants such as Bioprotektin and Supershield for spraying:

"надо взять такие готовые препараты как биопротектин и вот такой вот суперщит"
(You need to take ready-made preparations like Bioprotektin and this Supershield.) 1:26

These products are praised for their broad-spectrum effectiveness:

"они жмут и кладоспариоз... и фитофторозы... мучнистую росу и прочее прочие прочие заболевания"
(They suppress cladosporium, phytophthora, powdery mildew, and many other diseases.) 2:07

He also mentions that despite rain, treatments must continue because otherwise, significant crop losses will occur:

"надо делать проливы даже если дождь идёт"
(You must do treatments even if it is raining.) 2:27

Key points:

• Use biological fungicides like Bioprotektin and Supershield for comprehensive disease control.
• These products combat multiple fungal diseases simultaneously.
• Regular applications are necessary, rain or shine, to protect crops.
• Ready-made products are convenient but can be costly.

To reduce costs and ensure consistent treatment, Ivan strongly recommends preparing a homemade fermentation starter called Novosporin:

"берите вот такую закваску на васрин... начинаете экономить"
(Take this starter on Vasrin... you start saving money.) 2:46

He explains how to cultivate it at home using simple ingredients like potato broth or flour with sugar:

"можете делать картофельный отвар... мучную среду... столовая ложка сахара столовая ложка муки"
(You can make potato broth... flour medium... a tablespoon of sugar and a tablespoon of flour.) 3:16

The fermentation produces a bioactive solution that can be diluted 1:100 and applied to leaves, fruits, and soil:

"Один к 100 разбавляете и работаете... по листу по плодам подливаете в почву обязательно"
(Dilute one to 100 and apply... on leaves, fruits, and pour into soil.) 3:44

Key points:

• Novosporin is a cost-effective, homemade biofungicide.
• Made by fermenting simple kitchen ingredients.
• Provides continuous, mass treatment without the high cost of commercial products.
• Applied weekly to leaves, fruits, and soil for best results.

Ivan addresses viewers in hot regions like Uzbekistan, where peronosporosis and phytophthora are less common, but other diseases such as alternariosis and cladosporium are prevalent:

"у них пероспороза нет... но у них куча других болезней"
(They don’t have downy mildew... but have many other diseases.) 4:04

He encourages them to use local alternatives to the recommended products, which are widely available in their markets:

"у них на торговых площадках всё это продаётся... есть какая-то своя альтернатива местная узбекская"
(All this is sold on their marketplaces... they have their own local alternatives.) 4:37

Key points:

• Hot climate growers face different fungal challenges.
• Local fungicides and biofungicides can be effective substitutes.
• Use the same principles of prevention and regular treatment.
• Leveraging local resources is practical and efficient.

Ivan concludes by emphasizing the abundance of options and recipes to prevent phytophthora and other diseases in both greenhouses and open fields:

"давайте этими возможностями и воспользуемся и останемся с урожаем"
(Let’s use these opportunities and keep our harvest.) 5:08

He warns that just a few cold, rainy days can destroy the entire crop:

"пара холодных дней ночей с дождиком и всё сгорело"
(A couple of cold rainy days and everything is lost.) 5:14

His final advice is to protect your hard work and harvest by acting now:

"Берегите свои труды берегите свои урожаи"
(Protect your efforts, protect your harvest.) 5:19

Key points:

• Multiple effective treatments and homemade solutions exist.
• Early and consistent application is critical.
• Weather conditions can rapidly devastate crops if ignored.
• Protecting your plants now ensures a successful harvest.
