What Pesticides to Use on Watermelons for Better Growth and High Yield
Let's talk about the introduction of green plants and flowers that grow well and yield high with the use of pesticides on watermelons. The following article will provide you with detailed answers.
What Pesticides to Use on Watermelons for Better Growth and High Yield
Watermelons are a popular fruit in the summer, and to ensure healthy growth, it is necessary to apply pesticides during the cultivation process. Without pesticides, it is difficult to achieve a harvest and profit, unless it is organic watermelon that does not use pesticides. Commonly used pesticides include 5% Baisida, 3000 times sprayed under the ground mulch, 70% Aimeile, 10000 times 18.1% Furui, 3000 times 5% Ruijingt, and 1500 times drip root. After applying these pesticides, watermelons can grow well.
Watermelon Growth Cycle
Watermelons are annual vine crops, with a growth cycle from seed to seed, typically requiring 100-120 days. This cycle can be divided into four stages based on the characteristics of each growth phase: germination, seedling, vine elongation, and fruiting.Pesticide Application on Watermelons
The main pests of watermelons are: red spiders, small ground beetles (H), yellow melon beetles, and melon borers. It is difficult to achieve a harvest and profit without applying pesticides on watermelons. Generally, pesticides are applied every 7-10 days. Even if no pesticides are applied during the seedling stage for one month or in the later mature stage for half a month, 5-7 applications are still needed during the growth and fruiting stage. Organic watermelons do not use pesticides. Commonly used pesticides include 5% Baisida, 3000 times sprayed under the ground mulch, 70% Aimeile, 10000 times 18.1% Furui, 3000 times 5% Ruijingt, and 1500 times drip root.Commonly used agents for preserving flowers and fruits on watermelons include 50% Sukeling 1200-1500 times liquid, or 50% Puhaiyin wettable powder 1000-1200 times, or 50% Tobujin wettable powder 500-600 times, or 50% Daurin wettable powder 600-800 times, or 40% Guakuangning wettable powder 1000 times sprayed around the plants. To make watermelons grow faster, the main pest during the growth period is aphids. To control aphids, you can spray DDV + Dimethoate (1:1) 2000 times liquid on the seedbed before planting. During the peak fruit expansion period, the vines and leaves are lush, with poor air circulation, and aphids are more likely to occur, so strict pesticide control is necessary. To make watermelons bloom early and more frequently, apply 1% 6-BA solution 1ml to the peduncles of 100 fruits on the day of flowering, or apply 200-500mg/L 6-BA solution to the flower peduncles 1-2 days before or after flowering. Use anti-fall agents to spray the flowers 1-2 days after flowering. Pesticides to prevent pest damage to watermelons mainly include: yellow melon beetles in the early stage, aphids in the middle and late stages, and斜纹夜蛾 in the later stage. Watermelons are sensitive to organophosphorus pesticides; pyrethroids can be used to control yellow melon beetles; imidacloprid for aphids; and nuclear polyhedrosis virus or Bacillus thuringiensis for斜纹夜蛾.
Watermelon Disease and Pest Prevention
1. Choose high ground that is conducive to drainage for planting watermelons and promptly remove accumulated water from the field during the rainy season. 2. Chemical control. At the beginning of the disease, you can spray 80% Zineb 800 times liquid, or 70% Chlorothalonil 700 times liquid, or 50% Captan 500 times liquid, every 5-7 days, at least 3 times.The above is a comprehensive introduction to the pesticides used on watermelons for better growth and high yield, hoping to provide green plant enthusiasts with some relevant knowledge.
