Problems solved by technology

[0007] Currently, the only effective counteractions remain prevention-based, intervening through targeted pruning of infestation outbreaks and other targeted treatments; however, this involves the difficulty of constantly and carefully monitoring the state of the plantation, Intervention as required by individual plants or parts thereof, which is not readily available and / or involves high costs

Embodiment 1

[0034] 589.90 g of a mixture were prepared from the following active ingredients: 14.7 g pure lambda-cyhalothrin; 12 g benzisothiazol-3-one; 201.2 g pure chlorpyrifos-methyl; 59 g microencapsulated permethrin 25 / 75; 46 g Microcapsules Cypermethrin 40 / 60; Piperonyl Butoxide 76g; Pure Imidacloprid 178g. The product was dissolved in water to a volume of 1 liter to obtain a concentrated solution.

[0035] The concentrate was then diluted to 1 / 500 to obtain a ready-to-use solution; 15 liters of this solution were treated by watering palm trees (Ghana Leaf palm) administration. This solution is poured on the ground around the palm tree and further on the trunk and leaves of the palm tree.

[0036] After about half an hour, the surface of the palm was found to be free of live parasites; only dead parasites could be found in the soil around the plants or occasionally on the plants themselves. As a precaution, repeat the treatment every 40 days for prophylactic purposes. Plants ret...

Embodiment 2

[0038] Preparation of ready-to-use solutions for direct administration to palm trees having the following active ingredient concentrations: 0.02940 g / L effective-cyhalothrin; 0.02400 g / L benzisothiazol-3-one; 0.40240 g / L Chlorpyrifos methyl; 0.11800 g / L permethrin; 0.9200 g / L cypermethrin; 0.15200 g / L piperonyl butoxide; 0.35600 g / L imidacloprid. The concentration of all active ingredients is 1.1738 g / L. 18 L of this solution was applied to a palm tree infested with red palm weevil about 13 years old; using a pump with a terminal sprayer, the solution was sprayed on the ground around the palm tree and further on the palm tree (trunk and leaves). Within about 30 minutes, the surface of the palm was found free of live parasites; only dead parasites could be found in the soil around the plants or occasionally on the plants themselves. Three treatments are carried out in one year (March, June, September): thus, no further infestation takes place, restoring the palm tree treatmen...

Embodiment 3

[0040] The initial treatment of Example 2 was repeated on different palms using the same insecticide solution, but the solution was diluted to a total active ingredient concentration of 1.00 g / l, 0.90 g / l, 0.75 g / l, respectively. All of these solutions were still very effective on the red palm weevil, obtaining their total mortality within 4 hours, as shown in the table below:

Abstract

Synergistic composition able to rapidly and efficiently terminate Rhynchophorus ferrugineus infestation, in palms or other species suffering from this parasite. The composition comprises one or more among permethrin, cypermethrin, lambda-cyhalothrin; one or more among chlorpyrifos methyl, and chlorpyrifos ethyl; furthermore, benzisothiazolin-3-one, piperonyl butoxide, imidacloprid. The parasite dies shortly after contact with the product, infestation is terminated, and the palm remains protected against new attacks for a long time; the product is not toxic to the palm, on the contrary the plant recovers a level of health even higher than the initial one.

Description

technical field [0001] The invention belongs to the field of insecticidal products. Disclosed herein is a novel mixture of active ingredients capable of completely stopping the infestation of palms or other plants susceptible to this parasite by the red palm weevil. Background technique [0002] The red palm weevil (commonly known as the palm weevil) is a parasite native to Southeast Asia and Melanesia and is responsible for severe damage to palm plantations. Through the trade of infected individual palms, the species was introduced to the United Arab Emirates in the 1980s, and from there to the countries of the Middle East and the southern Mediterranean basin, reportedly to Spain in 1994, and later in 2006 Spread to Corsica and the French Riviera. It was first reported in Italy in 2004 from plants imported from Egypt; in 2005, the parasite was reported in Sicily and then spread rapidly to the central and northern parts of the country. A recent study assessed that the par...
