1、Foliar Spraying

Foliar spraying is the most frequently used way of applying pesticides for pest management in trees. However, the limits of spraying are extensive pesticide losses. According to Pimentel (1995), only 0.4% of active substance actually reaches the target pest.

2、Foliar application of glycine

Foliar application of these Gly-functionalized nanopesticides achieved effective prevention and control of RKNs due to the root-targeted delivery property inherent in this nanopesticide system, and such root-targeted delivery strategy opens a novel and efficient method to protect crops from RKN inva …

3、Concepts and applications of foliar spray for microbial inoculants

Herein, we will review recent scientific literature on microbial inoculants for foliar application and compare with respective commercial microbial products for plant growth promotion and biocontrol. All literature cited in the review was collected with a clear focus on foliar spray.

4、Foliar Sprays: A Comprehensive Guide for Gardeners

Discover the power of foliar sprays for your garden! Learn about different types, benefits, and how to apply them effectively. Improve plant health, control pests, and achieve optimal results with these essential tools.

foliar applications of fungicides and insecticides

Many fungicides are considered ‘protectant’ and are used as preventive sprays. These products should be applied prior to an infection becoming established. Other fungicides may have the ability to control some recently established infections; these are sometimes described as ‘curative’.

Making and applying foliar fertiliser and pesticide solutions

Getting the application of foliar fertilisers and pesticides right starts with making correct chemical solution mixtures of foliar fertilisers and pesticides. A series of steps are however needed to achieve this. The steps shall be described below using worked out examples.

Foliar Herbicide

Foliar herbicide application involves the use of equipment to coat the leaves of target plants with herbicide.

Foliar sprays for treatment and prevention

Often pesticide applications are best applied as a foliar so that they come in direct contact with the fungus, bacteria, or insect pest physically present on the plant. Compost tea has become a popular foliar spray because of its ability to suppress diseases as well.

When is the Best Time to Apply Fungicides for Foliar Diseases?

Fungicides have little to no curative activity, and curative use can promote development of fungicide resistance. Select fungicides that are labeled for the targeted disease and demonstrated to be effective. Obtain current information on efficacy and resistance.

Tackling pesticide overusing through foliar deposition and retention

In this paper, we outline the development of a range of methods for improving the retention of pesticide on plant leaves. We also discuss and highlight several key issues that merit more attention in the future.

Lychee is a tropical fruit renowned for its sweet taste and unique aroma. lychee trees are susceptible to infestations by various pests during their growth, which can harm tree health and compromise fruit quality and yield. selecting appropriate pesticides for foliar application to prevent and control lychee pests is critical.

When choosing pesticides for foliar application, the following factors should be considered:

1. Target Pests: First, identify the main pest species affecting lychee trees. Common lychee pests include the lychee stink bug (Tessaratoma papillosa), lychee fruit borer (Conogethes punctiferalis), lychee panicle borer (Cryptoblabes phyllostachys), and lychee leaf roller (Lymantria sp.). Understanding their behavior and life cycles helps select suitable pesticides.

2. Pesticide Ingredients: Choose broad-spectrum insecticides effective against multiple pests. Opt for low-toxicity or non-toxic formulations to minimize environmental and human health impacts.

3. Pesticide Formulations: Select appropriate formulations based on the growth characteristics of lychee trees and pest distribution. For example, use spray formulations for trunks and branches, and paint-on formulations for leaf-dwelling pests.

4. Application Methods: Follow label instructions or professional guidance for proper use. Ensure even coverage and avoid missed or overlapping applications. Adjust dosage and timing according to tree growth stages and affected areas.

5. Rotation of Pesticides: Rotate different pesticide types to prevent pest resistance. This reduces pest sensitivity to chemicals and improves control efficacy.

6. Integrated Pest Management (IPM): Combine foliar pesticides with other IPM strategies, such as maintaining orchard hygiene, pruning to reduce pest habitats, and regular inspections for early pest detection.

7. Environmental and Safety Considerations: Prioritize eco-friendly and human-safe pesticides. Use personal protective equipment (PPE) to avoid skin or eye contact with chemicals.

8. Expert Consultation: Seek advice from agricultural extension services, horticulturists, or local agronomists for professional guidance on pesticide selection and application.

effective prevention and control of lychee pests require a holistic approach considering target pests, pesticide ingredients, formulations, application methods, rotation, IPM, environmental safety, and expert consultation. By adopting scientific methods and technologies, lychee trees’ pest resistance can be enhanced, ensuring fruit quality and yield.
