To prevent peach rot disease in the rainy season

<

In recent years, some late-maturing and late-maturing varieties of peaches encountered rainfall after bags were removed, and the pathogens invaded by rainwater, resulting in a lot of rotting fruit and causing great losses to farmers. Therefore, to remind farmers to take precautions against peach rot disease during the rainy season.

Damage symptoms

The onset of disease began to appear light brown, water spots, near-round lesions. The lesion quickly grew out of the cotton hairy mildew, which is the mycelium, cyst, and sporangia of the pathogen. After 6-7 hours, the sporangia matured into black. The lesions spread very quickly, spreading to half of the fruit surface one day and rotating for 2-3 days. The disease organization is extremely soft and the farmers call it “water rot”.

In the rainy, high humidity, and high temperature environments, the lesions appear within a few hours after the invasion of the bacteria. The infected fruit produces a large amount of cyst spores within 1-2 days for new infections. Peach fruit bag after the rain is conducive to bacteria infection. Late maturing varieties are close to mature susceptible.

Prevention

1. Eight mature around harvest.

2. Remove and remove pests and rots in time.

3. Peach fruit should be taken within 1 day (up to no more than 2 days) after bag removal. The varieties with long picking time were sprayed for the second time 10 days after the first application. Do not bag peaches spray once in 7-10 days before picking. Use 25% Amisida 2000 times, 50% Tsuibei 4000 times, and 25% Kai Run 4000 times.

Precious Metal

Rhodium powder Rh≥99.95% Properties: silver-white metal, extremely hard, wear-resistant, also has considerable ductility Application: It can be used as raw material for electrical instrumentation, chemical industry and manufacture of precision alloys. Rhodium powder is based on the widespread use of ruthenium in the industrial industry. Since rhodium is a rare metal required by the industry, the industry price is slightly higher than that of general non-ferrous metals. Rhodium, one of the rare elements, has various uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and is also used as a polishing agent for gemstones. and electrical contact parts.
